Reread my application and used wikipedia to brush up on current medical/ethical topics.
What impressed you positively?
Out of all my interviews, MCV had the best waiting room and interview processing. You may think you're relaxed, but being able to send out a quick email, watch T.V. or surf the web does put you at ease.
What impressed you negatively?
My interviewer asked me questions that essentially required me to recite back my application packet. There were no really thought-provoking or deep questions.
What did you wish you had known ahead of time?
That all of my interview questions would come by reciting my application info, i.e. volunteer activities, research experience, clinical experience... I would have spent more time reviewing my AAMC application.
What are your general comments?
Overall a good experience. The tours were helpful. After my first interview, I would suggest taking my interviews in the afternoon. The tours always give an excellent idea of the pros of the school, and this question always comes up at length in the interview. I wouldn't recommend an afternoon interview for the first one however, since I was a little too nervous to pay attention.
