I also received an acceptance email from Waterloo 2 weeks ago after applying in January. They then wanted me to confirm/deny my offer within ~48 hours. I declined since I've already accepted another offer.
Hi there, I don't think Waterloo has interviews for their MHI program; the admissions decision is only based on your essay/grades/CV/reference letters!
Congrats and good luck to everyone who has an interview! Might be a silly question, but what do people generally wear for this? Is it full business formal (i.e. for women: dress shirt, blazer, heels) like med interviews or a bit more business casual like a job interview?
