Michigan State has each interview ask you three standard questions - my student interviewer just asked those three questions and two of them were just plain confusing. Not too tough though.
Emphasis on primary care, and the fact that the school has a Mission Statement that they abide by and stress - the gals in the admissions office are really nice too!
What impressed you negatively?
Interviewed by a first year medical student who had been there only a month or two, and the student had an anatomy test directly after our interview.
Second interview with a retired professor who just stared at me...
