What are your general comments? My interviewer was really nice and put me at ease - I'm just not all that sure that I made an impression on her.
What was the most interesting question? What will you do if you don't get into medical school? I was asked this too
What impressed you positively? Students seem happy with their school and like their faculty a lot. Housing and facilities are really awesome. The free lunch was great too.
What impressed you negatively? Interviewers read your file 15 min before the interview, so you don't have a good sense of what they remember and what they don't.
What did you wish you had known ahead of time? It rained like crazy, and my pathetic little umbrella did nothing to protect my suit.
