Just wanted to add a few things (Agree with all of the above about January being an important month and on the importance of being respectful to the rotation directors!)
I picked up some tips for interview scheduling that I thought I'd share here!
1) If you don't have a smartphone, get one before September, and set your email up to push.
2) Get a google account, and use the calendar app to keep track of your interview dates.
3) Get interviews and do the following: Brief 10 second celebration, then check your calendar to see which dates you are free on, then call the coordinator to schedule your interview.
4) Always schedule for the first available date. This was crucial to me scheduling 19 interviews with only two conflicts. Many people scheduled for the middle date and then got hosed when other December interviews came out.
5) I can stress the timing of the call to schedule enough! Near the beginning I waited an hour (didnt get the invite cause I didn't have cell signal) and only one date was left. I heard from coordinators that they would use the restroom and then hit send on the invite because they would be sitting at the phone non-stop for an hour. I believe at MD Anderson every date is full within 2 hours.
Generally speaking the earlier the invite the earlier the dates, so it works out pretty well. November dates are your best friend if you want to get 15 interviews in, you almost have to knock out a few in November. Also, don't forget about TYs. Get as many of those done in September/October as you can!! I was done with TY interviews, except for 2, by the end of October which is another reason I was able to get so many interview in.
Finally, be prepared for some super complicated scheduling. I had 5 interviews in 6 days in December. Monday, Tuesday, Thursday, Friday, Saturday. So rest up, because December and January are crazy.
