I had 4 interviews:
1) Recruiter. Easy interview, just asking about my background, and mentioning the multiple benefits of CB
2) Manager. A bit more in-depth than the previous one, some technical questions.
3) Teammate. Technical interview with some exercises to be solved in real time.
4) Teammate. Technical interview with some exercises to be solved in real-time.
I had the impression that my 4th interview didn't go well but they are desperately hiring right now, so it's time to join if you're interested.
