I applied through college or university. I interviewed at MongoDB (New Delhi) in Aug 2025
Interview
The interview process comprised of four rounds of interviews:
1. Coding Round - I
2. Coding Round - II
3. Techno-Managerial Round
4. Executive Round
For the coding rounds, the focus was primarily on logic building and optimization strategies with trade-offs of space and time.
In the Techno-managerial round, CS fundamentals such as concurrency, database indexing and normalization along with some knowledge of High Level Design were evaluated.
In the final Executive Round, general HR questions and some situation based questions were asked.
Interview questions [2]
Question 1
Given an infinite stream of integers, you have to print the average of the last N integers from that.
(Follow up) Given another integer x, print the average of the top N integers from the last N+x integers.
First had a phone call with a recruiter, then a technical assessment through a third party (with a person, not one of those websites), and then a three hour interview with three members of the team. Two of the three hour segments were coding, and the other was a behavioral.
I applied online. The process took 1 week. I interviewed at MongoDB (New York, NY) in Mar 2026

1. HR Call discussing the opportunity
2. Karat interview to solve as many leetcode as possible
3. Three interviews in 3 hours including a leetcode round, a behavioral round, and a Object-Oriented round.
* Initial screening calling with a recruiter and then a 1 hour technical interview call using Karat with a pair coding set up using a plain text editor not an IDE
