I spoke with a recruiter and engineer on the the team about my background. Then I had 4 technical interviews with engineers on the team. The process took 3 weeks. I was extremely impressed by the professionalism and speed of the process. The recruiter was kind and respectful, and always got back to me with 48 hours with my results on the prior round of interviews, and to let me know what the next steps would be. Interviewers asked interesting questions.
