Do all universities send interview invites by email or do we cone to know via UAC, QTAC etc ? Thanks.
In my experience (UNSW, JMP, and WSU) they are sent via email directly from the university.
ETA: also, and FYI more generally, every year since I’ve been here, without fail, people have panicked about not receiving interview invites only to find them, often days later, in their junk folders *cough* Dr.Potato *cough* so be sure to check there, too!
