Can we at least take some things for granted when advising new job hunters? Perhaps not. High school and college grads, and job seekers fresh from the military, if you're looking for a job, you know you need to dress correctly for the interview, spiff up your resume and polish your interviewing skills at a minimum, right?

And keep this in mind: As important as it is to say the right thing, it's just as important -- if not more so -- to not say the wrong thing.

CareerBuilder.com interviewed more than 3,000 hiring managers nationwide to find out the most bizarre things they witnessed during job interviews.

Here's a sampling:

  1. One candidate answered a cellphone and asked the interviewer to leave her own office because it was a "private" conversation.
  2. Another candidate told an interviewer he wouldn't be able to stay with the job long because he thought he might get an inheritance if his uncle died, and his uncle "wasn't looking too good."
  3. A candidate asked the interviewer for a ride home after the interview.
  4. A candidate said she could not provide a writing sample because all of her writing had been for the CIA and it was "classified."
  5. A candidate told the interviewer he was fired for beating up his last boss.
  6. A candidate for an accounting position said she was a "people person," not a "numbers person."
