Two interviews total. Smart, competent people. Solid business with upside. Most questions were what you'd expect for product management type positions. Approach to problems, past successes, failures, etc. No real surprises.
I ended up exiting the interview process as there just wasn't a great fit. Nothing wrong with them - or me - I don't believe. It's just the particular role they were hiring for was too constrained in a particular role as compared to what I was hoping for.
