My interview process consisted of 4 interviews. Interview 1 - This was a phone interview with the lead engineer. The main purpose of the interview was to assess my technical background and understand what devices/architectures I had experience with. It lasted roughly 45 minutes. Interview 2 - This was group interview with about 6 different team members. Again, there was a technical assessment, but mostly revolved around expanding what I had provided on my resume. They also took time to better explain the position and the expectations. Interview 3 - This was with the VP over the group. The focus was mostly why I wanted to work there and finalize any questions that I might have. Interview 4 (same day as 3) - Lunch with the team members - although it was in a much more social setting. The focus was merely to see how I interacted with the team.
