Talked with recruiter, then potential manager, then an array of related employees I would have worked with. The last part was over a 2 hour period. Generally pretty casual. There were 3 parts to the 2 hour final interview period. The first was to learn more about me. The second was similar but with a couple knowledge questions about autonomous vehicles. The last was questions about how I approach testing, a quick coding challenge related to that, and a set of questions to test my UNIX environment understanding (specifically asking about commands for debugging network issues and seeing resource management)

First was contacted by the HR who described the job and asked for my availability for the second round which is interview with Hiring manager and final virtual onsite with 4/5 interviews
