Yeah, I went on my home institution's interview, and we had 4: PD, 2 faculty (some people got the assosciate PD as one of theirs), and a chief resident. They weren't that long, and everyone I talked to said theirs were really laidback--just basically talking, chatting, getting to know you.
Interesting in that during my interview with the PD, he mentioned that he thought that at only about half the places would you interview with the PD and that many would just have an info session with him/her and that's it. I wasn't sure what to make of that (if anything). On one hand, I can see his point that it gives a message about a program and its relationship with the residents, but I can also see that programs are just super busy and that it might not be possible, especially on a day where a lot of people are interviewing. Anyone have any input?
