OK, so assuming that everyone here who was waitlisted/rejected has reported one or the other, a rough count is the following:
12 Rejections * 7.5 = 90
24 Waitlists * 7.5 = 180
This would represent a total of 270. About 700 people were interviewed, IIRC, and Willa(?) stated some 210 offers had been made, so we are missing 220 people still.... That means we probably still have a few more to be accounted for, but it sounds like of the remaining interviewees, 1/3 were rejected, 2/3 wait listed. That would put our wait list at around 327 people or enough to fill the class twice if all the current acceptances were turned down.... 😱
TL;DR
Est. Wait List Size: 327 Candidates
