They did say that applicants are accepted with or without interviews, but they are conducting more interviews, I guess.
I applied in R3, submitted the day of deadline, interviewed on the 23rd and got a phone call from my interviewer on the 25th. They put me on the waitlist because I needed to send an important document/letter from my company. They were sent yesterday, so I received an email today stating my status had changed. I checked the ApplyYourself portal and the decision status date did not change from waitlist to accepted. When I clicked on the link, though, the content of the letter changed, and it was an acceptance letter.
I already paid my $2,500 deposit, so USC, here I come! Fight on!!
