My experience was different because I applied for Directing and not MT, but I would love to share as well!
I interviewed and auditioned at Chicago Unifieds, which was kind of a mess, because Jed Harris (the rep from Carnegie who conducted my interview) had his flight severely delayed, and my interview time had to be shifted around. A lot of schools were canceling auditions altogether. But Jed was incredibly dedicated to the process. The CMU students he brought with him (who clearly loved and respected him) said that he had told them that, as long as he was given twenty minutes to eat, he would stay up all night conducting interviews if he had to.
My experience was overwhelmingly positive. I performed my monologue for him and then, as we reviewed my portfolio, we spoke - extensively and conversationally - about my interests, experiences, and the program. Jed was straightforward and concise. His biggest concern was that, because I have been such a successful actress throughout high school, I might miss that aspect of theatre by entering a program as intensely focused as Carnegie’s. But he also made it clear that that decision was in my hands moreso than his, and I did not interpret it as a suggestion that my chances for being accepted to the program were lowered.
We had a great connection. He told me that, of the 150 directing candidates he would see this audition season, he would only seriously consider around fifty, and he assured me that I was in that pool. He was exceedingly complinentary but also very realistic, making it clear that he could only accept four students, but that, no matter how his decision played out, I should not doubt my talent or my path for a moment.
