Munbue, those are pretty awesome stats.
It would be weird if you are only getting one interview so far.
Here's my advice to you, I would email or call every single school that did not sent you anything tommorrow and ask them to check the status. i think it's very likely that some stuff is missing, whether it be evaluation letters or application fee. Although some schools offers interviews without completed application package.
For those of you in the same situation, I would advice the samething, try to be little active and always call or email school if you haven't heard from them in a long period of time.
Good luck🙂
p.s. i would forget about adding backup schools, like nyu.......coz I think you have a great chance of getting into at least a couple of those schools.
