For the most part, it's sort of the normal interview questions, which was surprising. They'll ask about your personal history, what stories you want to make, and why. I wouldn't worry too much about that part and to tell you the truth, I purposely went in unprepared so I would be natural... Who knows if that was a good move or not. There are a couple of fun questions they'll throw at you which i won't spoil because I think it's actually better for you if you do it spontaneously. I learned more about my own film tastes than I did before!
The pitch, I can't really say. It's exactly what they say in the email--they won't try to surprise you. I'm not sure my pitch was ideal, but they weren't intimidating during the pitch or anything like that. I'd say maybe read up on how to give a good pitch. In retrospect, I probably should have done that, but I went in with this sort of "I'll be unprepared and natural attitude." I'll see if it works out.
As for the video samples, I brought in a DVD that I had submitted for other schools. I had thought it was to view during the interview, but it's actually for them after the interview is done--at least, in my case. So I brought in an unlabeled DVD expecting us to watch a clip and for me to take it back. I had to awkwardly right down my name on a piece of paper and slide in the dvd sleeve so I'd prepare the DVD a bit more than I did haha.
All in all, not too bad. Relax and don't worry too much. I will say that several of the interviewers might give off a cold demeanor, but I wouldn't take it personally. As the interview went on, I got the feeling that it was simply their personality.
Good luck everyone! And the campus is beautiful so explore if you can!
