Inital take home, followed by extension interview, followed by a coding challenge, followed by system design interview. The whole process took 3 months! The interviewers are usually really nice and want you to do your best.

The interviewer was nice, and he is friendly and willing to give hint, the question has 2 follow-ups, it was hard to complete in time. The question was not a typical LeetCode

Phone screen and then a full day of interviews. 3 pair programming challenges, a system design review and a prior experience interview. There was also an onsite lunch with a person from the company.
