Job Interviewing Do's and Don'ts

Interview DOs



* Dress appropriately for the industry; err on the side of being conservative to show you take the interview seriously. Your personal grooming and cleanliness should be impeccable.




* Know the exact time and location of your interview; know how long it takes to get there, park, find a rest room to freshen up, etc.




* Arrive early; 10 minutes prior to the interview start time.




* Treat other people you encounter with courtesy and respect. Their opinions of you might be solicited during hiring decisions.




* Offer a firm handshake, make eye contact, and have a friendly expression when you are greeted by your interviewer.




* Listen to be sure you understand your interviewer's name and the correct pronunciation.




* Even when your interviewer gives you a first and last name, address your interviewer by title (Ms., Mr., Dr.) and last name, until invited to do otherwise.




* Maintain good eye contact during the interview.




* Sit still in your seat; avoid fidgeting and slouching.




* Respond to questions and back up your statements about yourself with specific examples whenever possible.




* Ask for clarification if you don't understand a question.




* Be thorough in your responses, while being concise in your wording.




* Be honest and be yourself. Dishonesty gets discovered and is grounds for withdrawing job offers and for firing. You want a good match between yourself and your employer. If you get hired by acting like someone other than yourself, you and your employer will both be unhappy.




* Treat the interview seriously and as though you are truly interested in the employer and the opportunity presented.




* Exhibit a positive attitude. The interviewer is evaluating you as a potential co-worker. Behave like someone you would want to work with.




* Have intelligent questions prepared to ask the interviewer. Having done your research about the employer in advance, ask questions which you did not find answered in your research.




* Evaluate the interviewer and the organization s/he represents. An interview is a two-way street. Conduct yourself cordially and respectfully, while thinking critically about the way you are treated and the values and priorities of the organization.




* Do expect to be treated appropriately. If you believe you were treated inappropriately or asked questions that were inappropriate or made you uncomfortable, discuss this with a Career Services advisor or the director.




* Make sure you understand the employer's next step in the hiring process; know when and from whom you should expect to hear next. Know what action you are expected to take next, if any.




* When the interviewer concludes the interview, offer a firm handshake and make eye contact. Depart gracefully.




* After the interview, make notes right away so you don't forget critical details.




* Write a thank-you letter to your interviewer promptly.


Interview DON'Ts

Don't make excuses. Take responsibility for your decisions and your actions.



* Don't make negative comments about previous employers or professors (or others).




* Don't falsify application materials or answers to interview questions.




* Don't treat the interview casually, as if you are just shopping around or doing the interview for practice. This is an insult to the interviewer and to the organization.




* Don't give the impression that you are only interested in an organization because of its geographic location.




* Don't give the impression you are only interested in salary; don't ask about salary and benefits issues until the subject is brought up by your interviewer.




* Don't act as though you would take any job or are desperate for employment.




* Don't make the interviewer guess what type of work you are interested in; it is not the interviewer's job to act as a career advisor to you.




* Don't be unprepared for typical interview questions. You may not be asked all of them in every interview, but being unprepared looks foolish.




* A job search can be hard work and involve frustrations; don't exhibit frustrations or a negative attitude in an interview.




* Don't go to extremes with your posture; don't slouch, and don't sit rigidly on the edge of your chair.




* Don't assume that a female interviewer is "Mrs." or "Miss." Address her as "Ms." unless told otherwise. Her marital status is irrelevant to the purpose of the interview.




* Don't chew gum or smell like smoke.




* Don't allow your cell phone to sound during the interview. (If it does, apologize quickly and ignore it.) Don't take a cell phone call.




* Don't take your parents, your pet (an assistance animal is not a pet in this circumstance), spouse, fiance, friends or enemies to an interview. If you are not grown up and independent enough to attend an interview alone, you're insufficiently grown up and independent for a job. (They can certainly visit your new city, at their own expense, but cannot attend your interview.)

Interview Mistakes

Oversell ::: Trying too hard to impress; bragging; acting aggressively.

Undersell :: Failing to emphasize the fact that you have related skills;
discussing experience using negative qualifiers (i.e. "I have a little experience...").

Body Language

It is easy to create a negative impression without even realizing that you are doing it. Are you staring at your feet, or talking to the interviewer's shoulder? Be aware of what your actions say about you.

Lack of Honesty

The slightest stretching of the truth may result in you being screened out.

Negative Attitude

The interview is not an opportunity for you to complain about your current supervisor or co-workers (or even about 'little' things, such as the weather).


Lack of Preparation

You have to know about the organization and the occupation. If you don't, it will appear as though you are not interested in the position.

Lack of Enthusiasm

If you are not excited about the work at the interview, the employer will not assume that your attitude will improve when hired.

Rejection

Keep in mind that rejection is a normal part of every job search. For every position, if 100 people apply, 99 will be rejected.If you are rejected, it does not mean that you are not a good applicant. It simply means that you were not the best applicant for that particular job at that particular time. Don't get discouraged. Rejection happens to everyone and is not a reflection of you.
Consider each new application a new opportunity.

Interview Concepts

What is an interview?

An interview is a face-to-face meeting, especially for the purpose of obtaining a statement for assessing the qualities of a candidate. It further, indicates a physical meeting of people with two possible objectives:

1.
To obtain a statement or opinion – as is done when film stars are interviewed to get their views on any particular role, or when the prime minister is interviewed to get statement on the result of his discussion with another political leader.
2.
To assess a person for selection – such as interviews for jobs, admission to educational institutions, etc.

Preparing for an interview

1.
One of the most fundamental factors that contributes to the success of an interview is the time and quality of preparation made by you.
2.
The degree of preparedness for an interview helps reduce the uncertainty and anxiety prior to the interview.
3.
The amount of effort you wish to put into preparation is directly proportional to the importance of the interview.

What all you need to do before interview?

Learn about the organization

It is important to know the background of the institute you apply to. You must read its brochure and visit its website. It is important for the following reasons.

1.
Selectors cannot comprehend why and how a person can say he is keen to join an institute about which he knows little or nothing.
2.
From the interviewer’s point of view the good applicant is one who has done some homework about the organization.

What you must know is:

1.
A brief history of the organization.
2.
It’s main features
3.
Location
4.
Any important issue of the organization that has been newsworthy.
5.
Key people in the organization.

Refresh yourself on your subjects of graduation/post graduation.

1.
It is but natural that interviewers would quiz you on your field of specialization.
2.
You may like to go back to the principle text books and refresh your knowledge definitions, formulas, concepts and other related issues.
3.
An interviewer judges your ability to perform on future tasks on the basis of your past performance.

Through knowledge on claims made

1.
You should list your achievements, academic qualifications, prior experience and extra-curricular activities.
2.
Such achievements, or claims may be authenticated by certificates or photographs.
3.
The important ones may be photocopied and attached with the bio-data while the origins of all certificates should be nearly catalogued in a folder and kept at hand for reference should interviewer ask for them.


Tips for the interview

Entering the room

1.
Prior to the entering the door, adjust your attire so that it falls well.
2.
Before entering enquire by saying, “May I come in sir/madam”.
3.
If the door was closed before you entered, make sure you shut the door behind you softly.
4.
Face the panel and confidently say ‘Good day sir/madam’.
5.
If the members of the interview board want to shake hands, then offer a firm grip first maintaining eye contact and a smile.
6.
Seek permission to sit down. If the interviewers are standing, wait for them to sit down first before sitting.
7.
An alert interviewee would diffuse the tense situation with light-hearted humour and immediately set rapport with the interviewers. (But don’t tell him a joke!).

Lead the interview

A good interviewee would be quick to settle and begin to lead the interviewers.

Enthusiasm

1.
The interviewer normally pays more attention if you display an enthusiasm in whatever you say.
2.
This enthusiasm come across in the energetic way you put forward your ideas.
3.
You should maintain a cheerful disposition throughout the interview, i.e. a pleasant countenance hold s the interviewers interest.

Be brief

1.
Brevity is the hallmark of a good communicator.
2.
It is recommended that you volunteer information, but this must be done in lucid and to-the-point manner.
3.
An over-talkative or verbose person is instantly disliked and misjudged.

Don't Bluff

1.
If you not know the answer to a question, it is better to acknowledge it, rather than trying to bluff your through it.
2.
The interviewer will respect your honesty.
3.
In our experience, interviewers immediately take a stance of grilling a candidate if they suspect him or her of lying.

Humour

1.
A little humour or wit thrown in the discussion occasionally enables the interviewers to look at the pleasant side of your personality,. If it does not come naturally do not contrive it.
2.
By injecting humour in the situation doesn’t mean that you should keep telling jokes. It means to make a passing comment that, perhaps, makes the interviewer smile.

Interviewer fatigue

1.
Mostly interviews are conducted the whole day leading to fatigued minds.
2.
A little humour as a starter will ease the fatigued minds. However, if you do not have the knack of humour, it is better not to get into it.
3.
You must be proactive in offering information about yourself as the interviewers will be willing –listeners.

Be well-mannered

1.

1.

1. The way you conduct yourself reflects your upbringing and your culture.
2. It is good to project an air of humility.
3. Over confidence is often misinterpreted by interviewees as arrogance.
4. Avoid slangPolite statements are recommended.

Avoid slang

During the interview, slang will probably not be understood, and certainly not appreciated. Your communication needs to be as formal and explicit as possible.

Be poised

1.
Your posture during the interview adds or diminishes your personality.
2.
You should keep all certificates, testimonials and other relevant documents neatly on the table, preferably in a single file.
3.
Mannerisms such as playing with your tie, theatrical gesticulations, shaking legs or sitting with arms slung over back of adjoining chair must be avoided.
4.
It is vital to be conscious of your posture and gesticulations as they tell a lot about our personality.

Ask question if necessary

1.
Many interviewees believe that an interview is a one-way street, the hapless ‘victim’ struggling to be selected and the ‘all power’ being in whose hands lies the destiny of the interviewee. It is a myth.
2.
You may ask a question/clarify information if necessary. It is quite in order and much appreciated by interviewers.

Eye contact

1.
You must maintain eye contact with the panel, right through the interview. This shows your self-confidence and honesty.
2.
Many interviewees while answering, tend to look away. This conveys you are concealing your own anxiety, fear and lack of confidence.
3.
Maintaining an eye contact is a difficult process. As the circumstances in an interview are different, the value of eye contact is tremendous in making a personal impact.

Listen carefully

1.
It is imperative for you to listen carefully to the question being asked.
2.
If a question is not clear, it would be quite in order for you to seek clarification on the same.
3.
Seeking a clarification is far better than giving an irrelevant answer.
4.
It is very annoying for interviewers when an interviewee misinterprets the questions, and answers by saying something which is irrelevant.

Be natural

1.
Many interviewees adopt a stance which is not their natural self.
2.
It is amusing for interviewers when a candidate launches into an accent which he or she cannot sustain consistently through the interview or adopt mannerisms that are inconsistent with his/her personality.

Ten Rules of the Interview

1. Keep your answers brief and concise.
Unless asked to give more detail, limit your answers to two to three minutes per question. Tape yourself and see how long it takes you to fully answer a question.

2. Include concrete, quantifiable data.
Interviewees tend to talk in generalities. Unfortunately, generalities often fail to convince interviewers that the applicant has assets. Include measurable information and provide details about specific accomplishments when discussing your strengths.

3. Repeat your key strengths three times.
It's essential that you comfortably and confidently articulate your strengths. Explain how the strengths relate to the company's or department's goals and how they might benefit the potential employer. If you repeat your strengths then they will be remembered and—if supported with quantifiable accomplishments—they will more likely be believed.

4. Prepare five or more success stories.
In preparing for interviews, make a list of your skills and key assets. Then reflect on past jobs and pick out one or two instances when you used those skills successfully.

5. Put yourself on their team.
Ally yourself with the prospective employer by using the employer's name and products or services. For example, "As a member of __________, I would carefully analyze the __________ and __________." Show that you are thinking like a member of the team and will fit in with the existing environment. Be careful though not to say anything that would offend or be taken negatively. Your research will help you in this area.

6. Image is often as important as content.
What you look like and how you say something are just as important as what you say. Studies have shown that 65 percent of the conveyed message is nonverbal; gestures, physical appearance, and attire are highly influential during job interviews.

7. Ask questions.
The types of questions you ask and the way you ask them can make a tremendous impression on the interviewer. Good questions require advance preparation. Just as you plan how you would answer an interviewer's questions, write out specific questions you want to ask. Then look for opportunities to ask them during the interview. Don't ask about benefits or salary. The interview process is a two-way street whereby you and the interviewer assess each other to determine if there is an appropriate match.

8. Maintain a conversational flow.
By consciously maintaining a conversational flow—a dialogue instead of a monologue—you will be perceived more positively. Use feedback questions at the end of your answers and use body language and voice intonation to create a conversational interchange between you and the interviewer.

9. Research the company, product lines and competitors.
Research will provide information to help you decide whether you're interested in the company and important data to refer to during the interview.


10. Keep an interview journal.
As soon as possible, write a brief summary of what happened. Note any follow-up action you should take and put it in your calendar. Review your presentation. Keep a journal of your attitude and the way you answered the questions. Did you ask questions to get the information you needed? What might you do differently next time? Prepare and send a brief, concise thank you letter. Restate your skills and stress what you can do for the company.

SUMMARY

Because of its importance, interviewing requires advance preparation. Only you will be able to positively affect the outcome. You must be able to compete successfully with the competition for the job you want. In order to do that, be certain you have considered the kind of job you want, why you want it, and how you qualify for it. You also must face reality: Is the job attainable?

In addition, recognize what it is employers want in their candidates. They want "can do" and "will do" employees. Recognize and use the following factors to your benefit as you develop your sales presentation. In evaluating candidates, employers consider the following factors:

* Ability
* Character
* Loyalty
* Initiative
* Personality
* Communication skills
* Acceptance
* Work record
* Recommendations
* Outside activities while in school
* Impressions made during the interview

A function may have any number of default arguments. However all these arguments must follow all mandatory arguments. That is first you have to specify all non-default or mandatory parameters and then all default parameters.

What is XML Schema?

Document Type Declaration(DTD)

determines the name of the root element and contains the document type declarations

Elements

Elements are the main building blocks of both XML and HTML documents.

Examples of HTML elements are "body" and "table". Examples of XML elements could be "note" and "message". Elements can contain text, other elements, or be empty. Examples of empty HTML elements are "hr", "br" and "img".

Examples:

body text in between

some message in between

-----------

Attributes

Attributes provide extra information about elements.

Attributes are always placed inside the starting tag of an element. Attributes always come in name/value pairs. The following "img" element has additional information about a source file:

The name of the element is "img". The name of the attribute is "src". The value of the attribute is "computer.gif". Since the element itself is empty it is closed by a " /".

-----------

Entities

Entities are variables used to define common text. Entity references are references to entities.

Most of you will know the HTML entity reference: " ". This "no-breaking-space" entity is used in HTML to insert an extra space in a document. Entities are expanded when a document is parsed by an XML parser.

The following entities are predefined in XML:

Entity References Character

< <

> >

{

}

else // otherwise it is empty

{

}

//

}

}

Dervied Class:

///

/// Summary description for Class1.

///

public class DerviedB: BaseA

{

public DerviedB()

{

//

// TODO: Add constructor logic here

//

}

How do you choose 1 entry point when C# project has more Main( ) method?

In one .cs file there may be many classes having Main() method. While making the .exe you can define the class name as an entry point

CSC /main:classname filename.cs

The compiler throws an error if XML comments is not well formed

If the XML is not well-formed, a warning is generated and the documentation file will contain a comment saying that an error was encountered.

By declaring a base class function as virtual we allow the function to be overridden in subclasses

The derived class can provide new functionality by overriding the virtual method of the base class.

The method to be called is determined at the run-time depending on the type of the object calling the method, and it does not depend on the type of the variable declared to hold the object. The following example illustrates this point:

Suppose base class B and derived class D provide different implementations of a virtual method V(). Also suppose that there is a non-virtual method NV() of B which is overriden by D.

//In Main(), an object, obj, is declared to be of type B.

B obj;

//An object of D is created for initializing obj

obj = new D;

//Call virtual and non-virtual methods on obj:

obj.V(); //This call would execute D::F() since F() is virtual, and although obj is declared to be of type B, it contains object of type D.

obj.NV(); //This call would execute B::F(), looking at the declaration of obj.

This is the difference between virtual and plain overridable methods. Virtual methods execute slower than non-virtual ones because of run-time resolve of the method to be called. So programmer should be caeful while declaring a method as virtual.

Which of the following can not be declared as virtual

Both A and B are correct choices. Declaring a static function as virtual generates build error. Same with declaring member fields as virtual.

A static function can be called only using class_name.static_function_name() syntax, so there is no run-time resolve depending on the type of object, hence the term virtual does not make a sense in case of static functions.

In case member fields are overriden by a derived class the derived class methods will use the overriden variables by default, so there is no run-time resolve required for fields.

Sealed class can be inherited

sealed classes cannot be inherited as the sealed classes provides full functionality only the classes that have no full functionality can be inherited

Which of the following statements is not true for interfaces

Interfaces must always be declared as public so that they can be implemented or inherited

It is not permitted to declare modifier on the members in an interface definition

A is the correct answer. By default all the members in an Interface definition are public, so there is no need to declare access modifier public. It would be a compile time error otherwise

Interface members can not be declared as

Virtual keyword is meaningful when the derived class is expected to override base class method. Here a class will 'implement' a method of an interface, hence virtual is not meaningful for interface methods.

Static keyword indicates that a method or field is common to all instances of a class. For an interface there will not be any instance, hence static is not meaningful.

An interface and all its methods must be declared public for enabling classes to implement them.

Which method is implicitly called when an object is created

When an object is created Constructor is get called first. A default constructor is created automatically if we do not create a constructor inside a class.

Which of the following statement is invalid with regards to constructor

Constructors should have the same name as class name

Constructors have to be public so that class can be instantiated

Constructors can not be overloaded

Constructors can not be static

C# supports two types of constructor, a class constructor (static constructor) and an instance constructor (non-static constructor).

Static constructor is used to initialize static data members as soon as the class is referenced

first time, whereas an instance constructor is used to create an instance of that class with

keyword. A static constructor does not take access modifiers or have parameters and can't access any non-static data member of a class.

Since static constructor is a class constructor, they are guaranteed to be called as soon as we refer to that class or by creating an instance of that class.

It is not possible for a delegate to wrap more than 1 methods

False

In some cases you may want to call not just one, but two or more methods through a single delegate. This is known as multicasting. You accomplish multicasting by encapsulating the various methods in delegates, and then you combine the delegates using the Delegate.Combine shared method. The Combine method takes an array of delegates as a parameter and returns a new delegate that represents the combination of all the delegates in the array.

In C# events are actually a special form of delegates

False

Events are signals generated by an object to indicate occurrence of an action, while delegates are type safe function pointers.

An event is a way for a class to signal state change / an interesting action. Delegates are reference types which are used to encapsulate methods with a specific signature.

Events are declared using delegates. Objects which want to take some action on occurrence of the event attach their methods to the event handler, which is a delegate.

Which preprocessor directive are used to mark that contain block of code is to be treated as a single block

#Region and #EndRegion indicates a block of code which can be expanded / collapsed.

How are the attributes specified in C#

They are enclosed with in [].

For performing repeated modification on string which class is preferred?

StringBuilder class is preferred for performing repeated operations on string since its value is mutable. String class represents a text value which is immutable. All operations on string class which appear to be modifying its value actually return the new value.

So for modifying text contents StringBuilder class is preferred.

In order to use stringbuilder in our class we need to refer

We only need to refer System.Text namespace. StringBuilder Class is contained in the System.Text namespace. hence we need to add the following lines in pur code:

using System.Text;

Which of the following is not a member of stringbuilder

Answer is: Dsubstring();

Which method is actually called ultimately when Console.WriteLine( ) is invoked

AppendFormat() method is called.

What happens when you create an arraylist as ArrayList Arr=new ArrayList()

Once it will reach size 16 addding element in the arraylist, it will be automatically double the size.

What is the output of Vectors.RemoveAt(1)

Removes the object at position 1

GetEnumerator( ) of Ienumerable interface returns

GetEnumerator() returns a reference to System.Collections.Ienumerator class which allows a simple iteration over a collection

How do you add objects to hashtable

Actually operator "=" adds an element too.

The following example adds key-value

pair "x"-"value" to Hashatble h:

HashTable h = new HashTable();

h("x") = "value";

If A.equals(B) is true then A.getHashcode & B.getHashCode must always return same hash code

The answer is False because it is given that A.equals(B) returns true i.e. objects are equal and now its hashCode is asked which is always independent of the fact that whether objects are equal or not. So, GetHashCode for both of the objects returns different value.

Ans: False

What is the first step to do anything with assembly

Load assembly to running process

How do you load assembly to running process

Assembly class provides the following methods to load an assembly:

Which utility is used to create resource file

resgen

What is the extension of a resource file

.resx

A shared assembly must have a strong name to uniquely identify the assembly

True

Public policy applies to

Public policies are applied on Shared Assemblies.

Stream object can not be initialized

True

Which of the following has stream as the base class

BufferedStream,MemoryStream and FileStream all these 3 classes are inherited from System.IO.Stream class.

Which class use to Read/Write data to memory

MemoryStream

It is a nonbuffered stream whose encapsulated data is directly accessible in memory(RAM not files on disk).

To Configure .Net for JIT activation what do you do

Actually JIT activation is required for COM+ components which can be done by setting JustInTimeActivation attribute to true (choice A). For .net applications / components JIT comes in by default.

Which method is used by COM+ to ascertain whether class can be pooled

CanBePooled

How do you import Activex component in to .NET

An application called AXImp.exe shipped with .Net SDK is used.

This application does something similar as Tlbimp.exe does for non graphical COM components.

It creates a wrapper component that contains the type information that the .Net runtime can understand.

Net Remoting doesn’t allow creating stateless & stateful Remote objects

False

What is an indexer in C#

Indexer is a special syntax for overloading [] operator for a class. After defining an indexer, array syntaxes can be used for the class objects.

In the following cases which is not function overloading

Same parameter types but different return values.

Function overloading depends on the

1) parameter types

2) number of parameters

3) order of parameters

How to implement multiple inheritence in C#

Multiple inheritence in C# is achived by using Interfaces.

In C# a technique used to stream the data is known as

Serialization

Can static methods be overridable?

No

What is the use of fixed statement

The fixed statement sets a pointer to a managed variable and "pins" that variable during the execution of statement.

Without fixed, pointers to managed variables would be of little use since garbage collection could relocate the variables unpredictably. (In fact, the C# compiler will not allow you to set a pointer to a managed variable except in a fixed statement.)

Eg: Class A { public int i; }

A objA = new A; // A is a .net managed type

fixed(int *pt = &objA.i) // use fixed while using pointers with managed

// variables

{

*pt=45; // in this block use the pointer the way u want

}

What is the order of destructors called in a polymorphism hierarchy

Destructors are called in reverse order of constructors. First destructor of most derived class is called followed by its parent's destructor and so on till the topmost class in the hierarchy.

You don't have control over when the first destructor will be called, since it is determined by the garbage collector. Sometime after the object goes out of scope GC calls the destructor, then its parent's destructor and so on.

When a program terminates definitely all object's destructors are called.

How can you sort the elements of the array in descending order

int[] arr = new int[3];

arr[0] = 4;

arr[1] = 1;

arr[2] = 5;

Array.Sort(arr);

Array.Reverse(arr);

Is it possible to Override Private Virtual methods

No: First of all you cannot declare a method as 'private virtual'.

What does the volatile modifier do

The system always reads the current value of a volatile object at the point it is requested, even if the previous instruction asked for a value from the same object. Also, the value of the object is written immediately on assignment.

The volatile modifier is usually used for a field that is accessed by multiple threads without using the lock statement to serialize access. Using the volatile modifier ensures that one thread retrieves the most up-to-date value written by another thread.

What is the C# equivalent of System.Single

Float 32 bit

e.g. float i = 6.8F; // or 6.8f

By default, a real numeric literal on the right-hand side of the assignment operator is treated as double. Therefore, to initialize a float variable use the suffix f or F.

If you don't use the suffix in the previous declaration, you will get a compilation error because you are attempting to store a double value into a float variable.

A single line comments are implemented by

Interviewer's Guide

These are the general views of an Interviewer before,during and after an interview [in interviewer's point of view].

Interviewer's Guide Before the Interview

How would I create questions to evaluate interpersonal skills?

This depends on what work habits you include in your definition of interpersonal skills. Do you mean: teamwork; motivation; leadership; problem solving; empathy; adaptability; verbal communication; etc.? It would take about 10 pages of type to respond to your question without more information. There are 35 of these work habits included in the appendix of "High Impact Hiring." Please get a copy of the book and look at the list of work habits there. Then select 10 or 12 questions from the 175 samples included in the book.

What type of questions will tell me if a person is detail-oriented?

Try these questions:

Have the jobs you held in the past required little attention, moderate attention, or a great deal of attention to detail? Give me an example of a situation that illustrates this requirement.

Do prefer to work with the "big picture" or the "details" of a situation? Give me an example of an experience that illustrates your preference.

Tell me about a situation where attention to detail was either important or unimportant in accomplishing an assigned task.

Describe a situation where you had the option to leave the details to others or you could take care of them yourself.

Tell me about a difficult experience you had in working with details.

What type of questions will tell me if a person is self motivated?

Here are just a few examples: "Tell me about a time when you went out of your way to complete an assignment?" "Give me an example of a time when a project really excited you?" "Describe a time when you were unmotivated to get a job done?" "Tell me about a time when you did more than was expected of you." "Tell me about a time when you were given an assignment that was distasteful or unpleasant." Get the idea?

What's your opinion of having an applicant go through a timed writing/problem-solving exercise and asking questions based on the written product?

I have no problem with this approach as long as you can demonstrate that the exercise is job-related and you're clear about what knowledge or information you are looking for. If you plan to make this a part of your interview, be sure to administer this exercise to ALL candidates. I also encourage you to get work samples from a job candidate anytime you can. In addition, there are a number of standardized tests that you can include as part of your interview process.

How should I use a telephone interview?

Use the telephone interview to:

1. Fill in missing information on the candidate's resume;
2. Question the candidate to determine his/her level of interest;
3. Get a feeling for the candidate's communication skills;
4. Ask some questions to get a sense of the candidate's technical qualifications;
5. Decide whether to invite the candidate for a personal interview.

I was just hired as a supervisor and will be interviewing soon. How can I come up with the right questions to ask?

You can start by reviewing (or writing) the job description. Identify the key duties and responsibilities. Then decide what skills are needed to perform these key duties and responsibilities. Finally, draft some open ended interview questions that will make it necessary for the candidate to explain how they have actually applied these skills in the past.

How many questions should I ask in an interview?

Twelve to 20 experience based questions is about all you can ask in an interview that lasts from 45 minutes to 1 1/2 hours. However the number of questions you ask is based on the number of distinct skills that you are looking for. For each interviewer on your team, you should prepare at least two questions per skill that the interviewer is responsible for assessing. For example, if my team was made up of three interviewers and we were all gathering data about the same six skills, I would need to develop 36 questions (3 interviewers x 6 skills x 2 questions/skill).

Also, Don't give any two interviewers the same questions to ask. The idea is to get as much data from a candidate as you can without giving the candidate and opportunity to rehearse. If more than one interviewer asks the same question, you can see how this might compromise the quality of the data you get.

Would you recommend a structured interview?

Absolutely! I'm a strong believer in structured interviews, that is, interviews where the questions have been developed based on a well done job-skills analysis. This is the best way to insure that your interviews will be complete, consistent, and fair. Also, you will find it much easier to evaluate each candidate's qualifications based on their responses to your questions. My book "High Impact Hiring: How to Interview and Select Outstanding Employees," will give you all the tools you need to create high quality structured interviews that get results.

What is the value, if any, of questions like; "If you were an animal in the zoo, what animal would you be?

Zero value. These questions only satisfy an interviewer's need for ego gratification. The biggest problem with a question like this is that it has no "face validity." The candidate has no idea how to answer such a question and these questions smack of amateur psychology. My advice: stick to open-ended questions that require a candidate to describe specific job related events that reflect on their skills.

I am currently conducting a seminar on interviewing/recruiting. I need some examples of probing thoughtfully and any other suggestions on that topic.

I'm assuming by "probing thoughtfully," you are asking about techniques to get more detailed information about a candidate's response to an interview question. The process I recommend requires that you first ask the candidate to describe a specific job related experience (we call this a "behavior based question"). Here's an example: "Tell me about a time when you had to deal with a disagreeable person." In order to get complete information you'll need to ask the candidate to tell you such details as: who was involved, where did the event take place, when did it take place, what led up to this situation, what actions were taken by all parties, what was the final outcome.

In your book "High Impact Hiring" you recommend using a behavior based interview. Why?

A behavior based interview is the most practical for people who do not conduct interviews as a profession. This type of interview helps you focus on "what" a person can do (i.e. the skills they have) vs. "why" they do it. Behavior based interviews take advantage of the fact that people are creatures of habit and repeat patterns of behavior over and over. So, if we can get job candidates to recall specific job-related events, we can use this information to predict how a person will perform in a similar situation in the future.

Interviewer's Guide During the Interview:

What non-verbal signs do you look for while interviewing?

I'm not too concerned about nonverbal signs unless I see a definite conflict between what a person is saying and what their body language is telling me. If I see a large contrast, it's a signal for me to get more detail about the experience the candidate is describing to me. I also might ask the candidate for a reference in order for me to verify the facts I am being presented with. I do pay attention to body posture, tone of voice, and verbal pace. I like to mirror my candidates posture, tone, and pace in order to more effectively communicate with her/him.

The environment I work in is constantly changing (policy, leadership, etc.). I'm trying to find a question that would help determine a candidate's tolerance of change. Can you help?

Try some of these questions.

"Tell me about a time when you experienced a sudden or dramatic change in your workplace that had a significant impact on you."

"Summarize your experience working in a rapidly changing environment."

"Describe a situation you faced where it was difficult to cope with a change that was thrust upon you."

We have high turnover due to high level of "nasty" customers we have to handle. What type of questions would be good in determining what candidates are good at handling these people?

Before you begin to deal with the issue of "questions," you should ask yourself (and anyone who has in-depth knowledge of this position) -- "What personal characteristics (we call these Work Habits) are required of the jobholder in order to be successful?"

Your list might look something like this:

* Tolerant
* Slow to Anger
* Tactful
* Empathic
* Caring
* Friendly
* Confident

With the Work Habits identified, you now can develop a series of open-ended questions that will enable you to evaluate the match between a candidate's qualifications and the requirements of the job. Here are a few sample questions:

1. Tell me about a time a customer was rude or obnoxious on the telephone.
2. Describe a situation where you were close to losing your temper with an unhappy customer.
3. Now tell me about a time when a customer "pushed you over-the-edge" and you lost your temper.
4. Describe a situation where you where you found it necessary to refuse an unreasonable customer request.
5. Tell me about a time when you where successful in dealing with a very "nasty" customer.
6. Describe a situation where you went out of your way to accommodate a demanding customer.
7. Tell me about a time when you were able to become a friend to a customer who needed to feel that you cared about their problem.

Get the idea? Remember, these questions will get you information about a candidate's Work Habits, but not much information about their Technical Skills. You'll need to develop a list of these skills and create some questions that focus on the technical requirements of the job in order to build a more complete interview.

You recommend in your book (High Impact Hiring) informing the candidate they can look at the notes after the interview. I was wondering if you could just give me a few pointers on what notes to take?

All you need to include in your notes are description of the experiences that the candidate describes to you. I just list enough information in order to recall the experience when it comes time to evaluate the candidate's skills. For each example the candidate gives me, I like to know who was involved, where the event took place, when it took place, and what led up to this situation. I also want to know what steps the candidate took and what actions other's took in order to clearly understand the candidate's role. Finally, I ask about the outcome.

It's not necessary to include descriptions of the candidate's actions during the interview. That's not very helpful in evaluating their skills. Also, don't record evaluation or judgments in your notes. The time to judge comes after the interview is over.

One final point. Be sure to let the candidate know you will be taking notes so that you can remember the important details that the candidate shares with you during the interview.

How should I start the interview? Should I ask a question to help the person relax?

Start with a warm welcome to the candidate. Invite them to be seated and offer a refreshment. It's okay to ask questions like: "How was your trip? or Did you have any difficulty finding us?" Avoid questions or comments that relate to family or marital status, religion, or national origin. Continue with a brief self introduction explaining how you fit into the organization and describe your role in the interview. Briefly review the key duties and responsibilities for the job. Review the agenda for the interview and the schedule for the day. This should take no more than five minutes and now, you're ready to begin finding out about the candidate's qualifications.

How do you stop an applicant from giving run-on, rambling answers that don't answer the question?

Many applicants give rambling answers because they don't have a clue as to the level of detail you are looking for. A second reason may be that your questions are not focused on gaining information about a single skill but on a constellation of skills. A third possibility is that you are not asking behavior-based questions that require the candidate to describe in detail a single work experience. Finally, you need to tactfully interrupt a rambling candidate in order to maintain control of the interview. You might say something like, "That's interesting, but let's get back to the main point," or "You seem to be confused about what I'm asking. Let me clarify..."

How can I tell if a applicant is lying in the job interview?

There is a tried and true way to determine if an applicant is lying. Ask the applicant to describe a work experience they have had that is related to a specific job related skill you are attempting to evaluate. As the candidate responds, probe for detailed information. Be sure to take notes as the candidate responds. Then say, "Who can I talk to in order to verify the information you have just given me?" Be sure to contact this person as part of your reference checking process.

Interview's Guide After the Interview:

What questions are you allowed to ask the candidates' references as well as what information references are allowed to give?

"References" are often reluctant to give you information because they fear that they may be subjected to a lawsuit or other legal action. Fortunately, in most states, the reference provider is protected by law unless this person gives false or slanderous information.

Ask references to verify information you have received about the candidate's qualifications during the interview. I would also ask open-ended questions such as: "Tell me about this person's most valuable contribution. Summarize this person's performance in the technical aspects of the job. How well did this person's work habits help or hinder her/him? In what areas would this person benefit from additional training or coaching?"

Finally, ask: "Who else should I contact regarding this person's past performance?"

This is a brief description of the process you should follow. See "High Impact Hiring" for a more complete treatment of this subject.

How do I tell an applicant that they didn't get the job?

Before you contact the candidates that have not been selected, be sure that your selected candidate has been presented with and accepted your offer in writing. Following this, it's up to you to decide whether to contact the others by telephone. In any case, you should follow-up with a letter. It's not necessary to explain why the person was not hired unless you feel compelled to do so. In any case, your follow-up letter should remind the candidate that your company may be interested in talking with them should an appropriate opening become available.

Here's a sample script for a telephone contact.

"Hello , this is from . I'm calling to bring you up to date on the selection process for the position of you applied for. We were very fortunate to have an opportunity to talk with you and the other candidates and thank you for your interviewing with us. , I have selected another candidate for this position based on the best match between this person's qualifications and the requirements of the job. I wish you all the success in your current job search."
