Interview Process: The process consisted of 7 rounds, including a recruiter round. All of which were elimination rounds. I successfully cleared 5 rounds.

System Design Round: This round was not well-structured. The problem was given without explanation, and the questions were vague. There were 2 interviewers with similar experience. Most interviewers up to this point had joined MongoDB only 2 months prior, which may have affected the guidance provided.

Overall: The earlier rounds were manageable, but the system design round lacked clarity and proper evaluation.
