I am really, really excited about this project. I had a great time talking with them. I hope I get another interview! I still have many logistical questions, but it at least seems feasible and that there is some flexibility in terms of how the postdoc configures their responsibilities.
I have a few doubts about how I answered a couple of questions and wish I could go back and say more. I hate second-guessing myself on these things. But overall I feel good about it. I think they liked me and they seemed happy about my excitement for particular challenges of this project (e.g. data management).
Sounds like they have a couple more interviews to do and they might have a second round. Hopefully I'll hear something after my defense next week.
