The interview was a one-on-one virtual session. It started with a simple introduction, followed by solving a LeetCode problem on the HackerRank platform. Differences in experience might be based on the interviewer.

My first round experience was very good. The interviewer was super kind and very helpful, giving me a lot of advice and willing to share his thoughts.

The second round was less enjoyable. The interviewer didn't show up at the scheduled time, even after I sent an email to the hiring team. I received a reply one week later and had to reschedule. The process was almost the same as the first time; however, I could feel the vibe was not right between us.
