MongoDB Interview Experiences

Behavioral was honestly the most laid back part of the whole thing. Recruiter reached out first, 20 min call. Karat had a medium array problem and a follow up on edge cases. Final round was 3 sessions: OOP design for a data store, a graph DSA question then behavioral on how I learn new tech.

Karat screen went fine. Final round was three consecutive sessions. Object oriented programming design were alright but behavioral was weird, interviewer kept using hypotheticals instead of past experience questions

Phone screen was basically a resume-review and behavioural questions. Why company as well.

Karat interview first, binary tree path sum variant. Then three rounds with the team. OOP round wanted a generic cache with thread safety and I struggled with concurrency. Got cut after that
