What's up? Guess you received an invite. Congrats on that. I'm not sure if you are farmiliar with the search option, but if you search pritzker AND interview you get quite a high yield of threads that'll help you out. Here's just a couple.
it's great that you got an interview this early! pritzker was my first interview after labor day last year, and they were extremely encouraging and helpful during the interview day. basically you get there by around seven thirty, and there's muffins and juice for breakfast. dean robinson does a spiel about the top 10 things about pritzker and then you get a packet telling you where your two interviews are. i had a student interview in the same building. my faculty interview went well-she gave me positive feedback as i was leaving-but they asked a lot of thought questions so check the studentdoctor.com feedback and if you have time think about how you'd respond to stumpers. also you have a talk with sylvia-like ten minutes-so she gets to touchbase with you about things. for lunch, you get boxes and chat with some second and fourth years. all in all it's a pretty chill day.my tips are know your application pretty well. both my student interviewer and sylvia referred to specific answers. my faculty member didn't want to have any preconceived notions, so she did not read my AMCAS or supplemental beforehand. best of luck!
