Lengthy. Submitted an application, invited to a phone interview the next day, just to talk to someone who had the role I was applying for, pretty informal. Was then asked to take a proctored assessment, which took about 1.5 hours. Just some logic and basic coding questions. About a week after that assessment, I was asked to take another programming assessment, which took another 1.5 hours. A week later I was invited to interview, virtually this year, that would take place in 3 weeks. Started at 8:30 w/a product demo, then a 3:1 interview/conversation (3 interviewees, 1 current employee), then a 1:1 case study interview, then a check-in with an HR person and background check. Lasted about 3 hours total.
