Interviewed on 9/11 and didn't get the "application complete" notification until 10/2. No changes or notifications thus far.
Just so everyone is aware, the SCP stuff is basically new this year so things may be a bit off compared to last year. Also, they usually snail mail acceptances on the 15th of every month but that's not always the case. Going through the process last year, people mostly received acceptances the 17th-20th of each month, with a few exceptions. I think there was one time when they mailed out on like the 13th or something.
Also, if you interview in, let's say September, that doesn't necessarily mean you'll necessarily be reviewed for the October acceptances. Post-interview rejections occurred after waitlist notifications which was in May so, no news is good news in that regard. IU is the largest M.D. program in the country so just be aware that they may be a bit slower than other schools.
If anyone has questions, I'd be happy to help. I was on the waitlist last year but wasn't extended an acceptance so I'll try to help as best as I can.
