I got an email saying I was placed on the alternate list. Since you didn't hear anything today, then they probably haven't gotten to your file yet. Next decision date is on the 29 I think. Really hoping that there's some waitlist movement this year since MSUCHM is one of my top choices that actually offered me an interview. But it was my first MMI and I was super nervous, so I didn't feel like I did too well and probably the reason why I was waitlisted.
Looking at old threads, I couldn't really find any post-interview rejections. I think they either accept or put them on the alternate list, so I feel like this is basically a rejection.
