First had a phone interview, basic questions like "Describe a process you implemented" "What are you strengths, areas of improvement?"
Second, I was called in for an in-person all-day interview. I met with a finance guy, the assistant principal, the principal and the recruiter. They also gave me an hour to wander the building by myself and go in and out of classrooms and observe. Overall, I thought the interview was straight forward. The principal said he was really impressed with me and would get back to me within the week. I got the impression though that things were a bit disorganized, as a lot of the leadership were new and even some of the previous leadership that had left already had been around less than a year.
I never heard from them again. I politely emailed several times to the principal and the recruiter to follow up and never heard back. It has been months now. I'm still not sure what happened but this re-iterates the fact that they are disorganized.
