People rehearse the answers to questions they know will be asked. It says nothing about the individual or what they can add to a team. I used to ask people who indicated on an application that they liked to meet people, "If I could bring anyone into this room to meet you today, who would you most like it to be?". You'd be surprised how many people had never given it a thought. I also once asked, "If you woke up tomorrow and found you ruled the world, what would be the first thing you did?". Most clammed up, others said "I would cure poverty/hunger/wars, etc." The successful applicant said "Put my glasses on and get up, just like always" . Why not rehearse an answer to a daft question and, when an interviewer asks you something you aren't expecting, reply by saying "Ah, you've asked me the wrong question, you should have asked.........and then proceed to answer the one you want to.
