I once heard a story about a guy who was taking a polygraph test for a security clearance. Once the interviewer got him angry enough to decide he didn't want the job anymore, he answered the next question with "No, but don't ask me about sheep."
Actually asked to me:
1. What`s your worst chracter trait? I said: honesty, I`ve learnt honesty is not rated that high any more
2. If I ran into a friend of your`s, what would he tell me of you? Me (stunned): uuuuh, why don`t we try this, I`ve some numbers you can call.
3. Why would you take this job, it seems not to connect to your education? My answer on that was too serious, I didn`t get the job.
Then I was hired at a different company where the president spoke 65% of the job interview about his memories and vision and me being the flavour-of-that-day to his conversation.
