Question 1
What do you know about MongoDB and its culture ? What do u understand by SQL and No-SQL database and which is beneficial in which case.
Not bad, there were four technical interview rounds where each round they asked a question regarding coding and explaining my answer. But it was mostly just coding and algorithm and system design questions.
I applied through a recruiter. I interviewed at MongoDB (New York, NY) in May 2025
