I just got off the phone with the printmaking chair at CCA and the one question he asked that this thread didn't prepare me for was "Why make prints when you can simply draw or paint." Luckily I had a few arguments about this during undergrad so I was able to get through it. It's pretty media specific and he was just playing devil's advocate, but I thought I would share.
Otherwise yes, he asked if I applied to other programs (was able to get through by just saying how many), why this school over others, what the underpinning concepts of my work are, what artists I'm into, etc. I mostly got stumped bc I visited the school two years ago for SGCI and didn't remember if I met any faculty or what the demos were that I enjoyed ;s he was pretty cool about it though.
The 'have questions prepared' advice was really good. I asked if recent alumni stayed in the area or ventured elsewhere, what the grad student to faculty ratio is, and I found a course that I wanted more information about in the curriculum that he happened to be teaching, so that really got him talking.
