UF interview was pretty good. The dinner the night before was at a nice restaurant, Harry's (save room for bananas foster for dessert if you go there). The chief residents kinda run the interview day, they're pretty nice and helpful, but not the most social. The day I went they took us to M&M conference for lunch, and I got to meet a lot of the residents informally there, who all were real friendly and seemed happy. Call ahead and tell them if you are interested in a subspecialty, and they will try to get a meeting with someone in that department. Interview itself is really informal and low stress...there's 2 interviews, and neither of the interviewers had even read my file yet. It's a nice program, the biggest black cloud is the probation, but I got the sense that it's not a huge deal. They are very open about it, though, so feel free to ask questions. Dr. Edwards, the program director, is a real down to earth guy; feel free to ask him anything during the wrap-up session at the end of the interview day.
As for other programs, I liked Wake Forest, UAB, and Tulane...haven't been to Emory, Vanderbilt, or Baylor yet. UF is a good program, enjoy the interview.
