I did the interview with RISD GD 3yrs today, and it was pretty intense than I thought.
I interviewed with 3 professors, and they seemed to look through all of my portfolio, statement, and reference letters.
They asked me very sharp questions about my portfolio, like why did you use this kind of font and why are you so into some kind of topic so much.
I think they really want to know about who you are, and what is your interest to make a deep research for MFA program.
I cross my fingers to everyone! also for me!
