Since I couldn't find any info on here when I was doing research, I'm sharing SAIC interview experience for people who may be interested in the future.
The panel is with two faculty members--mine were Mary Cross and Nathan Hoks. Many of the questions came directly from my statement of purpose so I'm glad I looked that over again before the interview. They asked some standard questions: what are you reading; why SAIC; what classes are you interested in while here. Mostly it was just a conversation about major themes of my work and cross-disciplinary interests. They did praise my work--called out specific lines that stuck with them--but they did not ask me to explain or go over a specific poem.
I'd recommend not asking about funding during the interview. SAIC does an "interview weekend" and this includes a luncheon with everyone who was invited to interview, along with faculty, who can answer those financial questions (this happened over zoom this year). Getting together (again, via zoom) with current students was very informative as they were candid about representation among faculty (not diverse) and the cost. Decision will come within 2 weeks, I'm told, which includes merit based scholarship decisions. They generally give acceptances via phone call and then email and send a letter.
good luck to everyone in this great time of waiting!
edit:
Was emailed by Amaud Johnson from UW-Madison a little bit ago and notified I have been placed on a waitlist! Did not disclose the number of people also on the waitlist.
