hey - i've had a blast at my interviews. been to 8 so far, and uniformly the people i've been with have been really fun, and socially adapted ;-). all of them have been really relaxed and conversational, you do get some good questions but as long as you have familiarity with your work and some related topics you'll be fine. only once have i had an antagonistic interview, but there is nothing to do but keep your cool, do what you can, and take it in stride. the famous panel interview at washU isn't bad at all - i had a lot of fun doing it, a good experience. you are treated really nicely at all of these interviews, much better than your md colleagues (it looks like they get herded around a bit) ;-) gluck
