5 rounds of interviews, took 2 months, made it to the final round and didn't get the job.
First phone interview was with a Slack Recruiter who was the only person I communicated with via email for the entire process. She was very helpful and prepped me for next rounds of interview. Next was with the person who who I would report to, then 3 sets of interview with different team members. This process took 1 week but hearing back about the final descion took 2 months.
