There's a lot of info on Case on this website. I'm a student there, and I think Case is a great program. This year the 1 month rotation consisted of 1 week on sports, 1 week on joints, and 2 weeks on trauma. Sports and joints are at UH which is our private hospital. Your schedule will be reasonable - in at around 6-30 for sports, earlier on joints for prerounding to help the team. Done probably by 5 or 6, sometimes earlier (but there's usually cases going later if you want to stay and help). Most students take call about once a week when at UH, and it is not too bad (level 2 ER). Trauma is at Metro, our county hospital. You'll take Q3-4 call which is a lot of fun and you probably won't sleep. But you'll probably be able to go home early the next day. You'll also spend 1-2 days in clinic there, which is a good experience because you'll see patients and present directly to the chief resident.
Overally you'll have a good experience. Residents and attendings are student friendly, and you'll learn and have fun. I do believe that all rotators get interviews, although I'm not 100% positive.
If you have any more questions PM me.
