congrats on the interview invite. Pritzker was my first out-of-state interview, so I was sorta nervouse too, but staying with a student really took the load off for me. As discussed in other threads, this is a personal preference.
Nobody mentions it, but it's really 2 1/2 or even 2.25 interviews. The .25 is the dean, who has a paper with ~4 questions: what you did in the summer since AMCAS, what you doing this year, why UofC, and maybe one more. It's a total of 15 minutes, and he writes it all down like a nice secretary. Of course having questions showing interest is a big +, but that's for all the interviews.
The faculty interview was my toughest, partially because it started off with her asking about my chemistry research this summer and after a few minutes of struggling to explain to her (blank face) she shrugged it off as the stuff she never really understood, stating how her Physics-person [what the heck, it's not Physician, so what is the word I'm thinking of?] husband always trys and explains her research and she barely gets it. Eventually got talking about her kids and joked with her about helping her back pain and spending time with her kids @ the same time..
Student interview was good. Toughest series of questions I've had anywhere. He came on the tour with us, so I was already comfortable speaking to him throughout the afternoon.
