Easier said than done, though. So far I'm very dissatisfied with my current program (not specialty choice). I'm weighing my options now, one of which is to go thru the match again. I realize that things could get better here, but if I am to go thru the match I'll have to start the process soon. I could always not submit a ROL if things get better.
Anyway, I interviewed at far more programs than necessary, and I always tried to ask what I felt were appropriate questions. At every program, every resident I asked said they were happy, that they felt they were gaining great operative skills. When I asked about the things they didn't like, the answer was ALWAYS something trival, like bad cafeteria hours or difficult parking.
Realize that the unhappy residents often don't show up to the interview functions or hegde their answers. We don't want to be pegged as badmouthing the program.
