I actually interviewed 6/25 and was notified the first day they started offering admissions two weeks later on 7/8. I was waitlisted last year btw! When I interviewed last year on 7/25 I didn't hear about being waitlisted until Halloween. I also had coworkers apply/interview after me and get accepted last year. Other coworkers who had to wait two months to get accepted and I had another that got pulled of the waitlist one week before classes starting this May. All that to say that once you interview, it really does just feel like the luck of the draw! Keep your hopes up, keep trying. Do NOT compare yourself to others. You vs. you.
