Have you even applied? Because sometimes you get surprised as there’s no recipe to an interview. Also Not to be rude but You said it yourself. Subpar stats. It’s a competitive application cycle. In my opinion it is a very holistic review where everything matters and not one certain thing will get you an interview, as it’s based off your entire app. A low gpa coupled with low gre probably won’t get you far. I’d suggest emailing admissions and asking them what they think you can do to improve your chances for interview.
