At the beginning of last year (and I assume they did the same thing this year with the 1st years), a few of my classmates were invited to a lunch at the start of admissions season. The admissions people asked how they could better present the school to interviewees.
The main things people talked about were the creepy clown collection on the 3rd floor (yes, really), and what people described as a confrontational interviewing style. Dr. Krueger acted surprised when several people said that, and he insisted they didn't give the faculty any specific orders on how to interview people. Anyway, you're not the only people who got this feeling from the interviews here. If I had to guess, I'd say it comes down to the interviewers' personalities.
Several people also asked them to explain the rotations situation better than they did to our class, but I'm not sure how well they're doing that for those of you interviewing now. It's still a bit fuzzy even to most of us in our 2nd year here, but as we figure things out I'll try to fill you guys in as well as I can.
