Although it is very early, interview invites have started coming in and this thread seemed helpful last year. It would probably be useful to at least give the date the invite was received, the interview dates offered, and how you got the invite.
Mayo: via email on 10/15 for interview on 11/20.
Medical College of Ohio: via email on 10/18 for interview on 1/7 or 1/14. A buddy received the same email but was offered 12/3 or 12/10.
Good luck everybody.
