Now, You Ask the Questions

During the interview, there will probably be times when you will be one who asks the questions.

Clarification

The need may arise for you to ask the interviewer to clarify a point.  That is a normal in any type of conversation and would be a sensible thing to do.  However, you do not want to ask the interviewer to re-explain the entire subject because that might give the impression that you were not listening or that you had trouble comprehending.  
A clarification type question could be, " You say that this position is a typical salesperson position.  Could you explain what you consider typical ?" Or , " You mentioned that ABC Company does *blank*  Can you tell me how that works in practice?"

Don't Ask This 

Do not initiate questions about compensation ( pay, benefits, tuition reimbursement).  It might seem that you are more interested in the paycheck rather than the job.

Do not initiate questions about vacation or time off for the same reason.

Do not ask questions on the same subject.  It might make you appear one dimensional

Prepare 5 Good Questions 

At some point in the interview you will probably be asked if you have any questions.  You should prepare at least 5 questions.  The interviewer will be still be evaluating you as a candidate and having questions indicates that you are seriously interested in the job and perhaps have done some research on the company. This in also an excellent opportunity to find out some more information about the company so you can decide whether or not you want to work there.

Here are the type of questions that you should ask 

1. "If I work hard and prove my value to the firm, where might I be in five years ?"

2. "What are the opportunities for advancement?"

3. "How will my performance be evaluated?"

4. "What characteristics best describe individuals who are successful in this position?"

5.  "What is a typical day (assignment) [ for a position you are applying for ] in your company?"

6.  "What other positions and/or departments will I interact with most?"

7.  "What characteristics best describe individuals who are successful in this position?"

These are not the only questions to ask, but make sure that you structure your questions to gain pertinent information about the company and to demonstrate that you are a potential employee that is serious about the position and career.
