Copy/pasted from my post on last year's thread:
The first hour was Nelson giving a briefing on the school, their curriculum, research opportunities, etc. (essentially preparing you for any of the "why UTHSC?" questions you may get during an interview).
You will have two 1-hour interviews: one is closed-file, so they don't have your AMCAS in front of them (however, I am certain that they read your AMCAS at one point because my interviewer came prepared with a page of notes) - they are essentially trying to get an idea of you as a person. During this interview I got a few ethics questions, but it was mostly a stimulating back-and-forth conversation and didn't seem like an interview at all. I was prepared for/expecting current events questions or something about politics but I didn't get any, it was very relaxed.
The second interview was open-file and this is where you get "grilled" about your MCAT, any low grades, how you've spent any off-time, etc. It's more intense than the closed-file but nowhere near as stressful as some MMIs that I have been to where they are purposely trying to throw you off.
You have lunch with current students, get a tour of the campus, and get to see students in the anatomy labs/lecture halls. When I interviewed there were PT/OT students in the anatomy labs.
Overall it was very laid back, and very, very informative - they paint a good picture of their school and I didn't feel like they were covering up or trying to hide anything.
