After I applied on LinkedIn, I didn't hear back for a few months and figured I didn't get the role. Then a recruiter reached out and said they would like to chat. Talked to a the recruiter for 15-30 min, then interviewed for an hour with the hiring manager the next day. A few days later I was scheduled to interview with 4 separate people, each for an hour doing technical questions. Technical stuff covered System architecture, basic algorithms in python while live coding, SQL/data model discussion while whiteboarding.

I applied through an employee referral. The steps in order were a recruiter phone screen, a 45 minute technical deep dive of my experience with a team lead, a 4 hour onsite interview, and a 30 minute phone screen with the team's product liaison.
