I reached out through internal email to the hiring manager, met with them and their team, then was put in for a loop. My loop consisted of five sessions, with the hiring manager, two with other team members, one with a member from a related team, and one with the bar-raiser who is unrelated to the team.

2 phone interviews+1 on-site one. The first phone interview was conducted by hiring manager, the second one was by a PM in the peer team. And the second phone interview was just the day before Christmas!
