Overall, obviously, the specailty is not competitive. If you want to do IM you can- the same doesn't hold true for those other fields. However, at the top places, you need similar stats, I'd venture, to match in competitive fields. UMich and Wash U are very prestigious programs and I doubt you'd get an interivew without some substance on your CV. I interviewed at UMich this year and everyone I was surrounded by was very, very qualified. As for the super elites BWH, MGH, Hopkins etc. the only friends of mine interviewing there are AOA, >240 Step I- anecdotal, I know, and someone is bound to contradict me, but from they told me, the people they interviewed with were equally impressive. I got rejected from BWH. Woohoo.
