Two rounds of technical interviews were conducted.

1. The first round featured a simple, medium-level LeetCode question.
2. The second round was a system design interview, requiring the design of a notification module. The interviewer demonstrated good knowledge of the system.

Overall, the experience was not good.

After the second round, HR did not call back. Multiple emails were sent requesting feedback, but the response was "it's in process."
