Because it flowed more like a discussion, there weren't "difficult" questions that were asked for the sake of stumping me. But the interviewers certainly posed challenging issues for me to discuss, and were interested in how well I have thought out my decision.
SDN, practiced answering questions with a good friend and then someone who i didn't know as well. (because of the open-ended nature of the discussion format, it would be very helpful to practice answering questions and discuss your reasons for wanting to go into medicine with someone beforehand)
What impressed you positively?
honesty of my faculty and student interviewers. it seemed that they were both genuinely interested in my well being.
What impressed you negatively?
like many others, i got a really good feeling about the school.
What did you wish you had known ahead of time?
nothing
What are your general comments?
i was interviewing for post-bacc, which I understand is basically structured like an actual med school interview. I just didn't get the complete tour, and perhaps the questions weren't as specific when it concerned medicine.
but overall, it's very low stress. definitely prepare and take it seriously, but enjoy the ride, because they will try to make you feel very comfortable.
