What I was trying to drive home is, unless you're being discriminated against in any way during the med school interview, not every interviewer is going to hold your hand and ask you "so why do you like medicine sweetheart?" Some are going to be harsh. JHU rode me hard because of my low sGPA. Another school, in which I was accepted, grilled me on more than that. They questioned just about everything. So I wouldn't be surprised if an adcom treats interviewees that way.
I said "residency," not "residency interviews." Yeah, it's pretty much a job interview. I know that. But during residency, especially 1st year/internship, you're at the bottom of the totem pole. You'll be mistreated a lot by the hospital, attendings, and patients. Occasionally, the nurse who's been there "way longer than you" too. The administration of the hospital won't care about you or your patients, only about his/her pockets. Want a patient to stay overnight pro bono in the ER? Too bad, either treat the emergent issues and kick him out or somehow find the erroneous amount of money s/he needs to pay for the bed and the room.
Patients, no matter what, will hear what they wanna hear. Give them anything else? They'll ask for another doctor or just leave you all together (and I mean this in a general sense, not something like the flu or sinus infection.) Oh yeah, if you're 26 by the time you graduate, and if you work in a big hospital seeing a lot of older patients, get used to being called "young," "medical student," or "not a real doctor." It happens, and it won't stop until you bald or your skin wrinkles. Attendings want things their way, done in the manner they want, or else you're dead weight. They teach you how they were taught and some won't accept another way to do it.
But I guess n=1. Another point I was trying to drive home is: you don't get to walk out like that in the real world just because someone was harsh. I constantly get yelled at, even if I was right. Nature of the game.
