Hello everyone! I wanted to share this for any future applicants, because I know I searched for these before I auditioned.
I auditioned in Chicago at a hotel this week.
There was no check in, so I just sat down in a big room with everyone waiting. They gave a presentation, mostly comparing the BFA and BA programs, and the benefits of each. I was actually quite surprised that the BA is such a good option. There is a new dean who made some changes to the BFA program. In the BFA, you can’t minor, double major, or study abroad, and you are required to be in your class shows. BFA students have “blinders” that focus on acting and only acting. You don’t get any choice of classes to sign up for, and you are with the same 18-20 people for your entire time at USC. In the BA, there are BA-only shows, you can minor and double major, study abroad, and it is easier to have outside work. The faculty teaches both BA and BFA students.
Next we were divided into groups A, B, and C. The three groups rotated between prep time, the audition, and the interview (except for group B, who did the audition and interview first and then got dismissed early since they did not need prep time). My group had prep time first, and they said we could even leave or go to the Starbucks in the lobby.
I had my interview next. It was with the assistant dean of the School of Dramatic Arts. I’d say we talked for around 10 minutes. She asked me standard questions, such as my leadership skills, what I desired out of a college experience, why USC, and whether the BA or BFA program sounded right for me. She gave me her card and sent me an email (which she did for everyone).
My audition was with two auditors. I went last, and I did both monologues. They were both very friendly and smiled the entire time, and even gave me some chocolate at the end 
Overall, I had a very positive experience. I auditioned for UCLA as well, and the auditions had different vibes, but I preferred USC’s in general.
If you have any questions let me know!
