Hi,
I'm currently a first year at one of the chicago programs. In general, interviews were really chill. i interviewed at 10 places. no one asked me any medical questions. In general, they want to get to know you to see if a) you are a weirdo b) if it's a good fit. they usually ask about research, if you have any particular interests(liver? bid?), they also try to gauge your interest in the program/location( do you have family in the area, grow up in the area, or if can tell you are totally randomly applying there etc), if they know your letter writers they will talk about that. they do ask you if you have any questions which honestly you usually don't but come up with a few good ones that you can keep and just repeat in case needed.
here's some i used
#research mentorship, particularly in hepatology
#how many fellows secure faculty positions, how difficult was this.
#responsiveness to fellow’s suggestion in regards to changes in the fellowship
#what would you change?
#one particular strength of the program compared to where you did training
#changes you’ve seen since joining the faculty
#recent changes made, how it’s affected fellows
#involvement in resident education. Dynamic between residents/fellows/medical students.
Hope that helps!
