Hey Embee, sorry to hear you haven't heard back from any universities yet. For me, the process has been a total crapshoot. I got rejected from all of the universities I thought were safeties, and have gotten interviews at my reaches. I think universities care a lot about "fit" and random variables that are hard to control for.
That said, last week a bunch of people got into UNC without interviews or any contact from POIs whatsoever since submitting their application. So don't give up hope just yet!
