I always hated the "So tell me about yourself....." It's very bland, vague and mindless. If the interviewer had done his job, then there would be no need to ask that since my entire life is in that application.
Another is "There are no physicians in your family. How do you really know you want to do medicine?" I'm thinking "Is it something you have to be born in to??". And I got this question despite the experiences and very specific goals I have.
