So I had my interview earlier today and it went great, I think! We ended up conversing for almost 40 minutes and I really thought we would only get to talk 30 minutes max. I think I'll just put a summary of what happened in the interview and my insights on it so that maybe it might help someone out here.
It's very interesting how our conversation went, honestly. I did not expect it to meander around from one topic to another. While the faculty member did ask a few things that the other members were asked too (What kind of films/stories I want to do? How can I afford USC? What is my experience in filmmaking?), I was also asked a few other questions about my country and the issues we were facing were also asked (and I was even asked on my opinion on some of these).
Honestly, there's no real way to prepare for the interview, now that I look back to it. I did prepare for the usual questions, but, in the end, it was really just a conversation between a faculty member and an applicant. Maybe the more you think of it that way, maybe you'll feel less pressured heading in to the "interview." Having background not just in film, but also in life (aka being well-read or having many experiences and insights) really do help. So, don't be afraid to share stories and experiences if it's in line with the discussion at hand. At one point, I went "off-script" and told the faculty member that I was interested in exploring storytelling and narrative in video games, and that became a different discussion altogether and the faculty member was even giving me tips on how to start exploring that space if I really wanted to--whether it be outside USC or inside. It's not a class per se, and you're not in USC yet, but the interview is still a great opportunity to learn from a faculty member and to get their insights.
