3 rounds, all technical. There were easy to medium level leet code style problems in the first round, think sorting based challenges and sliding window. The other two rounds involved system design and experience in overcoming certain scenarios. The last round was pretty much the same as the second round. Everyone was friendly and professional.

Call with recruiter. Had one technical round which was system design. Then the recruiter told me the next round the hiring director would be looking for the qualities of a good engineer -- I thought this was going to be a behavioral interview. It was another system design meeting. The director seemed rushed and did not seem interested in me asking questions after we went through the system design. After the two interviews, the recruiter said they wanted to downgrade my listing to a senior based on my performance. And said I'd have to do "likely one more" technical interview. How many interviews do I have to do? No thanks. At that point I withdrew my application.
