Pretty straightforward, two online coding problems that solve. After submitting my application, I got an invitation for the first interview which is an online coding challenge. You are given 120 minutes to complete a two question challenge.

OA (2 hours) with two coding [problems] + leadership principle. After a round of interviews, I got the final interview, which had: * 3 coding [problems] * 1 system design [problem] * 4 rounds of leadership questions

It’s very hard. The whole process includes several different parts, and each part contained at least two algorithm problems. All of them are at least mid-level hard questions on GitHub.
