The first part was a call with HR and a Senior Product Manager. The next was a skills test challenge that involved a practical challenge, and I needed to scope and draft a presentation about a fake product feature I wanted to make. I demoed the feature for the last interview and also meet with their VP of Product and a Senior Product Manager who asked lots of questions around Product Management process and how I wanted to grow and develop. Really appreciated this approach and put me at ease. I didn't get an offer but it was a very rock solid interview process and you can tell they want quality people.
