I think my lack of Sharepoint 2010 experience will doom me. I think that overall, it did go well and even though I didn't know the answer to a couple of questions, I did know the answer to many that seemed to surprise them. Regardless, one look at my resume shows that I know how to run an IT environment no matter which obscure detailed question I might miss, so I don't think I humiliated myself. I don't think I'll get it but it was great practice and I got along with their team well -- none were assholes, which makes it easier.
