Residents are humans, some are bad and some are good. I had an extremely negative time on my OB/Gyn rotation despite working my tail off and expressing interest in the field from day one. I got involved as a witness in a lawsuit due to how terrible one male attending treated his patients and the sexually suggestive comments he made during Gyn exams (which I reported him for and was ignored), I had two residents who would constantly bicker and try to put me and the other medical student in the middle of their arguments to take sides, I had a tech slap my hand repeatedly for doing what the attending asked during c-sections because the tech was too busy having side conversations to do her job, one resident even left her post on two separate occasions after being distinctly told NOT TO LEAVE by the chiefs to 1) get a mole removed from her face in the middle of a work day and 2) travel to Vegas for her bachelorette party which then resulted in one of the chiefs having to drive 2+ hours for a robot case which then was done without a second person certified to assist with the robot (illegal in the state they were practicing in), I was turned away from most patient rooms because of being male/med student (which is understandable but still sucks) and saw the same for male residents and attendings. But yeah, I’m probably just entitled to expect more than that from physicians. And I’m definitely a misogynist for standing up for my female patients after essentially being sexually assaulted by a male attending.
I realize that not all OBs are bad, I had some that were genuinely awesome, but I would still generalize that many OB Gyn residencies are very toxic, after experiencing several such programs first hand and being told similar stories from several more. Even my close friend going into OB/Gyn has hated nearly every rotation/interview because of how toxic the people are, but she loves what the training will lead to so she has to suffer through it.
Also, to say that you can tell which med students are going to have a good/bad time on the rotation based on how you perceive them in the first day or so is just as subjective and as much of a generalization as anything else that’s been said here tbh, and shows that you are prejudging them, thereby increasing the odds of having said outcome.
