I recently interviewed at OU, and I hope to get a detailed review up on the "Interview Reviews" thread within the next couple of days...not much time to do it tonight. Briefly, friendly residents and attendings; chair is passionate about getting involved in organized medicine; OU has excellent PGY-1 setup and moonlighting opportunities. Main drawback I see is that no heart, lung, or liver transplants are done at OU Medical Center...those are done by a private hospital across town.
Until I can get something more detailed posted, hope this helps!
