There were 4 round in total. I failed at third round. The phone interview with HR and the first round of technical interview were great. They are responsive and helpful. However, the second round technical interview with engineering lead was not joyful. The interviewer didn't open his camera and not focus on the interview at all. It should be the basic things for the interview. Besides, I expected much more interaction with the interviewer when we were discussing the system design question but the interviewer was quiet. It seems like he was working on something else during the interview.
