"So, do you have any questions?" This is your signal the interviewer is done conducting her part of the interview, and is opening the door to any concerns/questions you may have regarding the potential job.
I'm amazed at people who let this opportunity slip through their fingers and end their interview with a shake of their head and a weak, "No, not right now."
Always, ALWAYS ask questions. Even if you have been asking questions throughout the hour, have back-up questions ready for the end. It shows you came prepared and are interested in making sure not only that the employer wants to hire you, but that you want to work for them.
A company doesn't want to waste time training a person who is going to quit after the first month. They will appreciate you taking the time to make sure it's a good fit all around.
"But I don't know what to ask."
Before you go into any interview, take the time to research the company you're applying with. Do an Internet search, or call their front desk and ask if they have a Web site. Go to the public library and ask a reference librarian for help.
Yes, it's boring, but if you're the one candidate out of ten who knew (thanks to your research) about the new branch the company is opening in Atlanta, who do you think the employer will be inclined to hire?
I take with me into every interview what I call "standby" questions. These questions are non-specific and may be used in almost any interview.
You may not ask all of these, and some may have been answered during your interview. If you can ask two or three pertinent questions, and then end with the final question above, you'll be in good shape.
If you're nervous about forgetting your questions, carry some type of leather binder or legal pad in with you to the interview. This serves several purposes.
Number one, you have your questions written in front of you. When the interviewer asks if you have any questions, don't hesitate to open your binder and say, "I have several I wanted to ask you. You covered most of them already, but I did want to know…" Again, you come off as prepared, organized, and professional.
Second, if you're a hand wringer, holding a binder gives you something to grip and resist the urge to twist and turn those hands.
Finally, you ought to be carrying several copies of your resume and references in with you. I also suggest you carry a completed application form. Many companies now require both resumes and applications. Can you remember the address and telephone number of the place you worked three jobs ago? And what was your supervisor's title there?
Carry a completed application with you as a cheat sheet, so you have all pertinent information handy and ready to go.
There is one final question you should always ask. "When may I expect to hear back from you?"
Find out what the interviewers timeline is so you know when you may follow up with them if you haven't heard anything.
Now then, any questions?
