1st time going through the interview, HR=>Hiring manager=>Engineer manager=> another supply chain manger (Director was absent but no rescheduling) => Co-worker Process was pretty standard, but director no show and asked someone to step in wasn't ideal. Got rejected without knowing why, but got notified after 2 months that the position is still open, and got the job 2nd time around.

R1: Recruiter screen, R2: Hiring Manager, R3: 5 interviews (3 team + 2 cross functional), R4:Executive. The hiring process was a bit long, but it meant that I also could understand more about the team
