I think it went well. The PI didn't have any questions for me, just said that it was a matter of whether I wanted it, and whether they'd be able to afford a small enough pay cut that I'd still want it. He offered a department with fewer assh*les than biomedical research as an incentive, and I have to say, I'd be okay with losing money for that.
So, I guess we'll see how the other interviews he has lined up go, and what he can swing with fiscal (he was going to meet with them as I was leaving).
