I also interviewed at Mayo, but for the AZ 4-year program. I had the same questions about "prestige" vs the MN campus, etc. From asking students and doing more research, I don't think it will be viewed any differently from MN. Mayo Clinic Alix School of Medicine is technically a national system, and it is apparent from their admissions that it is all a unified system. So from my understanding, once you graduate- whether it be AZ or a 2+2 program, you will simply just be a MCASOM graduate- there will be no official designation as to what campus you were trained on. Obviously your campus location will come up in interviews and what not, but again I really don't think it will matter a whole lot. Mayo is Mayo and its reputation holds weight. Best of luck when decisions are released in Feb; I'm definitely crossing my fingers!
