Around 5-6 rounds with employees. You get to meet them and they get to ask questions. Nothing too special, they are very nice. I assume that they later decide together if you suit their needs.
Interview questions [1]
Question 1
Stuff about coding, and some low level system questions. Synchronization primitives and system functions.
First there was a fairly easy live coding assessment.
Onsite: Panel interview followed by some coding assessment.
One interviewer didn't show up: not a great look. Another interviewer botched a question.
One Telephonic Interview followed an onsite, which included chat with the CEO, a technical round with one of the engineers from the planning team and a coding interview. There was also some puzzle type questions
