First round with manager, 1 technical hour Second round visit the side. 5 Hour. 2 engineer ask me about technical questions during 1 our hour each one 2 manager ask me about the process where I am familiar 1 engineer invite me to eat together and just talk

Very formal, but not rigorous. Phone interview was good, recruiter was not technically savvy, so having the ability to explain previous experience at a non-engineer level was an advantage. Interview was with 4 other engineers and two managers. Second round was with CTO and VP (1:1 interviews).
