Just got an interview invite (Batch 17). I will most likely be declining it. Here's some information on current waitlist status for all of you (part of the email that was sent to me):
"At this time, the Class of 2020 is tentatively full (outstanding offers fill the class). Should someone decline our offer or withdraw from the class, his/her position would be offered to an Alternate. In past years, we've offered acceptances to as few as eight or as many as 75 to the class from the Alternate List between the time the class is filled and the day classes begin!"
