First round was with the CTO. It was a pleasant experience and very chill. We went over quick behavioural questions. The next round was a technical interview. During the technical interview, the staff engineer was really hard to work with and not cooperative. He seemed so stuck up and would give one word answers to my questions. This broke my confidence to an easy problem I could solve in 20 minutes. I'm glad I failed that interview as I would not want to work on a team with someone like that. At the end, the CTO sent me insightful feedback. Yes, the CTO is amazing and I believe so is the company culture.
