This was an internal interview process. It started with an informational session with the hiring manager, a roughly one-hour discussion about what the team does, my current responsibilities, and why I was interested in the position.

Next, there were three technical interviews, each about an hour long.

Finally, there was an interview with the Engineering Director for that group, which lasted 1.5 hours. We discussed why I thought I would be a good fit for that team.
