I feel like their class is full already, that's why they're so slow on reviewing the interviews. If the class is not full yet they would have released acceptances way earlier to fill up the seats. If they release acceptances this late I don't know how many students are going to accept the spot as they already have other plans like they already moved in to their new apartments, some schools start super early, like in July. USC used to be my top choice, but it seems like the school is not thinking for its future students by doing this, so it's not worth attending tbh. Some schools are super quick on it, one school I interviewed at and did not hear back after 3 weeks, I emailed them told them that they were my first choice and I had a deposit due date for another school soon. The day after the admission called me to offer me a spot. I'm done with USC for causing all the stress to the students who are waiting for them. I interviewed April but probably drop my spot if getting accepted.
