recruiter was super nice and friendly. the process is kinda lengthy as you do a karat -> final round interview, which is a technical which covers over the karat. would have been nice to know how/what to prepare for each part of the technical interview since I was not prepared for React questions
Interview questions [1]
Question 1
Data structure and algorithms. also react questions
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 college or university. I interviewed at MongoDB (Gurgaon, Haryana) in Jan 2026
Interview
Total 5 rounds highly tiring. First round is phone screen followed by a karat technical round(DSA + CS fundamentals). Then 2 technical rounds about projects, previous experience + more DSA. Finally last HR round.
Interview questions [1]
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.
I applied online. I interviewed at MongoDB (Dublin, Dublin)
Interview
Recruiter reached out after seeing my CV, and scheduled an initial call. Later got interviewed with Karat which asked leetcode easy/medium questions, which I didn't do so well on due to pressure.
