Reliable Robotics Systems Architect interview questions

I had an initial call with the recruiter. I then had a meeting with the hiring manager. I was assigned a take-home assignment and had a week to complete it. They scheduled a call with a member of the team to review my assignment with me. If I had made it to the next round they told me that would have involved going on site for four 1-hour interviews, the first of which being a presentation of my assignment to a panel.
