I've had one interview. It was very friendly and relaxed, mostly discussions of
"why rheum?",
"where do you see yourself in 5 years?",
"are you interested in clinical/bench research, why/why not?",
"do you have a particular disease in mind you would like to study/specialize in?",
and of course, the dreaded, "what questions do you have for me?"
The first IV or two this stuff is fun to talk about, but once you're trying to force it for the 7th interviewer of the day it's hard to feel sincere
As the day went on I kind of went off my stock talking points and spent more time in discussion of what these people see as the future of rheum, what job prospects are like in their area for academics vs. private practice, what their fellows have gone on to do, what they focus on in their practice, etc. After all, the people you're talking to are experienced rheumatologists with a more knowledgable eye on the field than yours, so even though it's an interview you can still learn something about the field from them!
