I had one online interview with someone from the West Coast. Once I passed that, it was a virtual on-site interview with 5 CK members, including the HR manager. This included 2 technical rounds, 1 design round, and 1 system design round.

All interviews went well, except for the system design. During the SD interview, I was unsure of how to present the question. After stating the question, when I tried to gather expectations/requirements for the design, the interviewer directly jumped to a solution-first approach and asked me to write a high-level design.

After a week, I received a response from the recruiter. Even though my technical rounds were great, I was rejected due to the System Design round.
