There were 3 rounds:

1. HackerRank: Included SQL and 2 DSA questions.

2. API Design: Given an API, I had to transform the output into specified formats with 3 variations. The interview experience was good.

3. DB Design (Parking Lot): The question was easy. I felt the interviewer was under pressure. He randomly blurted out that I was not replacing him and, till the end, even after all other rounds went well, this person kind of made it his life's mission to not let me through. Turns out he was asked to leave a few months after, so things were pretty tough for him, I guess.

4. System Design: Don't remember the exact question, but it wasn't too difficult. We ended up talking about my open-source contributions, and it was a good chat.

5. Director Round: A bit technical, then we dwelled into a behavioral round. It was a nice conversation, and I was assured of a nice work environment if I were to join.
