What's the most unusual thing a candidate did in a job interview? Fall asleep? Disappear? Bring his/her mom? A CareerBuilder.com survey of the most outrageous interview mistakes candidates have made, according to more than 3000 hiring managers and HR professionals in the US, listed the top ten job interview blunders as:

1. Candidate answered cell phone and asked the interviewer to leave her own office because it was a "private" conversation.

2. Candidate told the 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. Candidate asked the interviewer for a ride home after the interview.

4. Candidate smelled his armpits on the way to the interview room.
