To answer your question:
I arrived about 20 minutes early. We signed in and then we went to a little slideshow about the school. It lasted about an hour. Then, we went to our interviews. My interview lasted about an hour. I had a 4th year med student and a med school professor (a nephrologist). They asked me the basic questions (motivations, extracurricular, etc). The hardest question they asked was "what cell in the body would you be?" I had thought of what organ I would be, but not what cell.
Another student said that she got all ethical questions..but I think most people I talked to had a mixture of questions. Most had two interviewers, but some had only one. The interview was overall relaxed, though. After the interveiw (mine lasted about 50 minutes) we went on a short tour of the school. Hope that helps.
