First job - forget about money, you want to work with the best medical care system and people you can find. Fellowship - is in part a personality test. It is a dress rehearsal for a real job. DO NOT argue with anyone unless it is a life and death patient care issue and your mentor is unavailable. Curb any narcissistic traits you may have. You are only going to be there a year, everyone else has been there much longer. Difficult patients - get a witness ASAP. Worst borderline I ever helped treat was during my fellowship. Fortunately she went after someone else, but it could easily have been me. She made my hair stand on end, honest.
