So there's two separate "interviews" one is an open file which is 1:1. My interviewer looked over my app as we talked but I felt like it was mostly to guide the conversation. He also stated that he had some questions "that the school would like for me to ask" but I got the sense that it was more-so just to provide jumping off points from one conversation piece to the next. That being said he did also ask some ethical based questions as well. He also invited me to use examples from work&activities section to expand on my responses.
Second part of the interview I had a physician & M4 student who went back and forth asking q's that many would consider to be more classical interview questions. I think they each had 3 for me to answer in a 30 min timeframe so if you're doing about or under 5 min a response you should be golden. Not sure if this section was open file but I don't think so.
Overall. Very chill but very long day (9:15 central time to 3:30 central) They have a student Q&A session the night before that is super chill (I was wearing PJs the entire time) and then the next day have more presentations, Q&A sessions (both before & after your actual interview sessions). My advice, re-read your application & secondaries, identify areas of service that are passionate to you, and stay engaged because there is a strong likelihood that whatever type of community service you are interested in they have med-students working on.
