I interviewed here this past week and thought I'd share a little about my experience.
Firstly, the panel interview was great. It's either 2 or 3 adcom people and 3 interviewees. You get a few group questions/tasks (one which requires a semi-substantial amount of time) and interviewees are asked individual questions. It runs about an hour and 15 minutes. The individual questions would all probably be categorized as the bizarre kind for which no one can prepare. One guy on my panel had quite clearly over-prepared himself and regurgitated answers which were inappropriate for the question asked (mostly because they were so... weird). I thought it was an excellent opportunity to demonstrate your ability to engage a group of peers and think critically about a situation. In addition to discussing alien (and I mean extraterrestrial) education and all-powerful machines, there were some ethical situation questions thrown around. The 1-on-1 interview was very short and seemed relatively unimportant in the scheme of the interview process.
The tour was pretty informative. Got to see the anatomy lab, study spaces, lecture halls, etc. Unfortunately we couldn't go into the hospital because there was some sort of infection/virus running rampant. Students seemed really excited about the school and receiving their education Chicago.
At the final info session of the day the Associate Dean shared these statistics with us:
~700 interview invites go out
~1/2 of those who interview are accepted within 6-8 weeks
class size of 170
generally little, if any, waitlist movement
If you've got any other questions feel free to post them and I'll see if I can produce an adequate reply
gl all!
