I am in a similar situation. I plan on trying to get a second SLOR from my Oct rotation in as old boy suggested (i hope i can impress them soon and have a good letter in before the end of the month). I remember seeing a few residencies say on their site their deadline is Nov 1st but you can get them a LOR to them by Nov 15th as long as they know it is coming, don't remember which though.
So if an applicant has at least 3 letters total (2 LOR and 1 SLOR), as long as the residency doesn't specifically say they require 2 SLOR's then the applicant will be reviewed, correct?
Additionally when do most programs start sending out interviews? Is it only after the entire app is complete after Nov when all the deans letters come out?
Thanks
