Uconn is an easy interview, but a long day. by the time I got to the pbl session at the end of the day, I was a bit exhausted-- they didn't feed us lunch until 2, so make sure you get a good breakfast before you arrive.
Otherwise, the only thing I found was that they seemed to focus a lot on the strength of the dental program during the tour, and that concerned me a bit, because it seems to me they should have focused more on the med school. that being said, it was a student tour guide, and who knows how much training they get.
The students are great-- everyone is so friendly. The get to know you session can be a bit stressful (all the interviewees and the dean of the school) but the rest of it is really laid back.
