"Next Tuesday, December 15, is the day we release decisions to all first round applicants. Here's what you can expect:
Some time on Tuesday - most likely close to noon Boston time - you will receive an email from HBS MBA Admissions indicating that your decision is available. When you log into your account, your decision letter will be there.
Important note: No need to wait around by the phone or jump every time it rings - we don't make any phone calls in advance of the online notification. Really. Admits will start to receive congratulatory calls later in the day.
Applicants invited to join the waitlist on December 15 will receive a follow-up email later in the day on Tuesday from Eileen Chang, waitlist manager. The waitlist will be comprised of a mix of candidates who have been interviewed already and those who haven't.
For those candidates who are not admitted: I'm sorry, but we just can't offer personal feedback about your application. Even if we had the staff capacity to do this during the application season, it probably wouldn't be as helpful as you wish. The vast majority of applicants are certainly academically qualified to be here and would bring something interesting to the classroom. The challenge of selection is different from the process of evaluation - in our effort to bring together a diverse and textured class, we make many very tough calls.
We appreciate your patience...not too much longer to wait!"
