Long time listener, first time caller. I interviewed at BID 2 weeks ago; my impression was quite the opposite as those previously posted. I interacted with a gaggle of residents, both the night before at dinner, and the day of during lunch. I found them interesting, relaxed and easy to chat with--they all seemed to be happy there and had good things to say about the program. It seems like they hang-out with each other quite a bit outside of work, including monthly happy hours and other resident trips (I was told skiing and fishing trips) paid for by the department The work hours seemed reasonable. There were six other applicants on the day I interviewed, one of whom was an olympic gold medalist! I am interested in pain, and their program is one of the best in the country. Apparently they routinely take 2-3 residents/year into the program.
Anyway, I (obviously) really liked the program; I interview at the other two Harvard programs next month, so I cannot as of yet make a comparison.
