Went to a campus visit at Haas this week and met with a Admission Advisor during the visit. Wanted to summarize what he said:
-Round 2 applications have been overwhelming this year. This probably means that Haas wouldn't start looking at waitlist candidates till after 3/1. If you looked at the posts from last year Haas didn't get to review the waitlist pool till pretty late. This is probably going to be the case this year.
-If you were waitlisted then you probably had something wrong in your application. Haas is trying to see if you can figure out what that weakness is and if you will address it in your update letter. (Kinda feel like a guessing game).
-Haas drops off waitlist candidates who are furthest from San Francisco first and slowly make its way in. This means if you are a CA resident you probably wouldn't get dropped off until August. Unless you get off the waitlist of course.
-It is very much a waiting game. So keep them updated............once a month.
