The interview process involved an online test which was quite luck-based. Following that, there was a first online interview. Then, a second online or offline interview with senior team members. The final stage was an interview with the CEO. The second interview, which could be either online or offline, ranged from basic to intermediate difficulty. Some candidates got easier questions, while others faced tougher ones, but all were related to basic to intermediate problem-solving, similar to LeetCode problems. They typically presented two easy or medium problems, and if you answered those well, the interviewer would move on to more challenging questions.

The interview process was quite long. First, there was an online MCQ exam that was proctored with AI. Then came the first technical round where they asked some basic Leetcode problems and questions about my CV. The second technical round involved more Leetcode problems, but a bit harder this time, and SQL problems, focusing on advanced Postgres features like JSON and arrays. They also dove deep into web dev concepts like JWT, auth, Docker, and rate limiting, and asked about my past projects and work. The final round was an interview with the COO, which included a quick 10-minute DSA problem followed by a conversation. There was also mention of a background check and an offer.
