Entrevista
3 Rounds, 2 with engineers on the team(1 hour each) and 1 with PM(40 minutes). Everything is what you'd expect, questions usually derive from your cv and they can range from computer networking to distributed system. There are coding questions but they are very standard. Out of 3 interviews I was stuck on 1 of them slightly, but I finished the solution after the interviewer giving out hints.
