Mongodb

I went through four rounds of interviews at MongoDB for a Software Engineering Intern position, cleared the online assessment and the first technical interview, but was ultimately rejected after the techno‑managerial round due to weak CS fundamentals.

I had a technical phone interview focused on concurrency and parallelism where I was asked to design a web crawler and explain my design approach.

Applied for senior software engineer role at MongoDB. Had three rounds of interviews, including topics like intersection of two sets, read write lock implementation, and word break problem. Despite solving all questions within time, the interview resulted in a rejection.
