A little hope for those of you who didn't get an interview at McMaster - I didn't last year either but got accepted directly to another school. Programs weigh things differently so try not to put yourself down too much!
I would say email them and ask for clarification! I know I'm going to DAL so I didn't think to much about it. I've emailed questions to admissions before, they're very friendly and helpful!
I still have not gotten an email. I emailed them to see if I would be getting one, and it sent back an automatic response. Hoping to hear anything soon just to know for sure!
