Had a 45-minute call with the VP of Product & Innovation. She spent most of the time explaining the organisation and we chatted a bit about my experience. I'd say it was pretty casual. The second interview is a case study that you're expected to spend 4-6 hours of your own time on, but to actually do what they're asking takes much longer. The task is broken into two separate parts. Part 1 is essentially a product strategy and roadmap, including GTM and monetisation. Part 2 is a backlog of feature ideas that are prioritised, along with metrics, addressing a problem they actually have. They expect you to organise and present ALL of this in 1 hour. Everyone seemed to enjoy the presentation, I responded to all questions. I was told I didn't get the job because they were looking for someone who had experience working with larger technology teams...something that could have been sorted in the first conversation without having me waste 8 hours of my life.
