We are told again and again that we should have these "interesting cases" prepared for interviews, because we will invariably be asked to present a case at some point. But what are they really looking for? Should I discuss the one case that was truly bizarre, but which I was only peripherally involved in? Or should I discuss the case that on paper is actually pretty mundane, but at the time influenced my future career choice? Also, many of these interesting cases were over 6 months ago, some over a year ago. I don't have the records and I certainly don't remember the actual lab values, parts of the history, etc. Should I just fill in these gaps with what I think I remember? It's probably not worth it, but I'm really stressing about this.
