Two one-hour long interviews. One with a panel one with a singular interviewer. Both interviews asked the same style of questions with the final interview asking many follow-ups eating into any of the time I had to ask about the position itself.

Very straightforward, more of a discussion than an interview. If you stick with organizing examples around their "purpose, values, principles" (PVP) theme, you cannot go wrong. They also provided an opportunity to ask them questions, so have a few prepared - this was the best part of the interview.
