I was Waitlisted R1 post-interview. The feedback letter I received afterwards said that they had no feedback to give, and that I presented strong overall candidacy, etc etc.

Regardless, I submitted two material updates, a Letter of continued interest, and an endorsement from a SOM alumni. Still waitlisted again today. Feeling pretty bummed I didn't get a call today, but there's nothing else but continue trying to get off this WL. Congrats to all who got in today.
