One piece of advice that I have is that when you are interviewing, just be alert and notice if the house staff seems generally unhappy. Any/every place may have the occasional unhappy person, but if the overall impression is that house staff seem beaten down and unhappy, run the other way, no matter how nice the PD SEEMS at the interview, or how good the lunch is at your interview, etc. Also, try to talk to some of the interns, not just whatever upper level person or one chief residency that has been prescreened/picked to sell you the program. This last one is harder to do...you'll probably be hustled around the hospital all day at your interview, and it can be tough to find anyone to talk to. Sometimes the dinners that many IM programs have the night before can be a good place to find out the things they won't tell you on the interview day, though you have to be a little careful who you ask your questions to, and careful about the impression you are making @the same time. If there are any graduates of your med school in various east coast residency programs right now, then trying to get their contact info and emailing them might be a great way to find out about programs.
