You won't really get anything good out of those questions - everyone has boring, safe answers ready for them.
IMO, you're much better off asking behavioral questions that force the interviewee to think a little bit and (hopefully) react off the cuff. Here's a
huge list of behavioral interview questions that you can look at.
My favourite, however, is not listed. It's this. Ask the person's name, verify some basic details, and then say, "What would you say if I told you that the interview was over and that we were not interested in pursuing you as a candidate for this position any longer?"
There's varying shades of correctness, but the answer I like the most is the one where the interviewee says they'd be surprised and would like to inquire as to what went wrong so that at the least they could correct the error in their next interview with someone else.
Fun little question, really puts people on the spot.
