I interviewed there a few days ago and it was a great experience. I was also prepared to be "drilled" with some tough questions, but the interview was nothing like that. They were extremely friendly, laid back, and the interview (that was with a dental resident and a D4) was just a friendly conversation.
The day starts out with a few presentations, followed by a tour of the dental school, then lunch, then a 2 hour Q&A session with Jeff, of the academic deans. During the 1-hour lunch, the interviewees get to mingle and ask questions to Professors, residents, and dental students. Half way through lunch the interviewer finds you in the crowd and takes you into a room for the "formal" interview (which was actually pretty laid back for the most part).
For all those of you who got an interview there already, one word of advice: relax! They emphasized the fact that they do most of their screening pre-interview. So if you get invited for one, chances are pretty high you'll get accepted. In fact, the first slide of the presentation were admission statistics. They accept around 70-80% of their interviewed applicants, put 10-15% on the waitlist, and the remaining are either put on hold or rejected.
I hope this helps. PM me if you have any other questions.
