They follow very similar process as other companies does. Starts with quick recruiter screening call and then 1 hour Coding call. If all good then 1 hour system design and then hiring manager call. I've heard about their culture from other professionals in SF but never have I ever encountered such unprofessional people. From recruiters to hiring manager, their behavior truly justifies their culture.

1 phone screen followed by 3 onsite rounds - 1 coding, 1 behavioral, and 1 project deep dive. Questions were pretty straight forward and fair. I did not get the offer though since I was out of practice.
