Also, I didn't see on their website where they listed a date that you would hear back by.
I did see this though:
"Alumni Admissions Advisory Committee members will make every effort to contact the students in their areas who have met the priority deadlines, and students who do not meet these deadlines may still have their names forwarded to alumni committees in their areas. However, because of the large number of applicants and limited number of committee members, we cannot guarantee an interview for every applicant. If we are not able to offer you an interview opportunity, please be assured that it will not affect your chances of admission in any way."
