A good, incisive question on your part will give the interviewer the impression that you did your homework, know your stuff, and have a good understanding of the position that you are applying for. On the other hand, a poor question will give your interview a weak finish, and will linger with the interviewer.

In your preparations for any job interview, it is critical that you come up with 3-5 potential questions to ask your interviewers at the end of the session. You will not necessarily ask all those questions; two is more than sufficient. But some of your potential questions may get answered during the course of the interview, and others may appear irrelevant once you have more information. You should discard these questions; otherwise you will give the interviewer the impression that you weren’t pay attention or understanding what was going on. That is why you should come up with more questions than you really need – so you have something to ask no matter how the interview goes.
