To come back to the OP--if you get an interview, it means that you are good enough. And if you show up for that interview, well, you've got a darned good chance.
We have 1257 applications today in ERAS. We'll invite 90 or so for interviews. Maybe you were #150 or so on our first sort--but it doesn't mean that you are worse than #40 ( or better than #400 for that matter ). For whatever reason, something caught our eye, and we want to meet you in person. And we hope you'll really like us, that you really DO want to do psychiatry, and that you'll actually want to train here...because honestly, it's all kind of a blindfolded dart game at a certain point.
(I'll vent more about it when it's all over, but I really wish there were an easier way to find the really good residents in this sea of sincere-sounding personal statements, OK board scores, and occasionally equivocal letters of recommendation. I suppose if I were vistaril, I'd just exclude anyone who's not a US citizen from a US allopathic school or maybe the Big 4 Caribbeans or a DO school we've heard of before...but then I'd miss out on some of the best young colleagues I've ever had the privilege of working with...)
