When you're in the hot seat, there's a good chance your interviewer will turn the tables at some point and ask, "Do you have any questions for me?"

When you have the floor, you'll want to take full advantage of the opportunity to show that you've done your homework and to determine if the job is a good fit.

But it's imperative that you put just as much thought into what you ask as you do your responses to their questions, because your queries may reflect your knowledge of the company, your work ethic, your level of professionalism, and your interest in the role.

"In the first interview, you'll want to be sure to ask the right questions. Ask about the job and company; not questions that can come off as self-serving and give the impression you may not be a team player or be willing to give 100%," says Amy Hoover, president of the job board Talent Zoo.

She continued: "The sole purpose of the interview is to determine if you are a good fit for the company, and if it's a good fit for you. All the other issues and concerns should be addressed during negotiations after the job offer has been made."

Here are 17 questions you'll want to avoid during the first job interview, as they may do more harm than good:

What does your company do?
Questions like this will make you look unprepared. To avoid that, never ask anything that can easily be answered with a Google search.

What will my salary be?
Hold off on the money talk.

Will I have to work long hours?
This says, "I'm lazy."

How soon can I take a vacation?
Wait until you're offered the job before you start asking these types of questions.

How quickly could I be considered for a promotion?
Focus on the job at hand.

When will I be eligible for a raise?
This may tell the interviewer that money is the only thing you care about.

Will I have my own office?
Does it really matter?

What happens if I don't get along with my boss or coworkers?
The interviewer may wonder if you've had problems with colleagues in the past — and they may even assume you're difficult to work with.

Will I have an expense account?
There's really no reason to ask this in the interview. Plus, it sends the wrong message.

Are you married?/Do you have kids?/etc.
Never, ever ask the interviewer any personal questions.

Can I make personal calls during the day?
This one says you're not 100% focused on your work.

I heard this rumor about the CEO. Is it true?
You should never bring gossip into a job interview. It's highly unprofessional.

Do you monitor emails or internet usage?
This question will raise red flags — something you definitely don't want to do in the interview.

Do you do background checks?
This one may also make the interviewer suspicious.

Can I arrive early or leave late, as long as I get my work done?
Don't try to make adjustments to the schedule before you've even been offered the job.

How did I do?
This one puts the interviewer on the spot. If you really want feedback, wait until you get the offer or rejection, and then ask in an email what you did well, or could have done better.

Did I get the job?
You don't want to appear too eager.

Bonus: The worst question of all is the one you never ask.

"Not asking questions can be just as bad, or worse, than asking terrible questions," says Deborah Shane, a career author, speaker, and media consultant. "It can reveal a lot about your communication skills, personality, and confidence — and it can leave the interviewer with a bad impression of you."
