I applied online. The process took 3 weeks. I interviewed at MongoDB (Los Angeles, CA) in Aug 2025
Interview
Consisted of 3 back to back 1-hour long interviews, with 15 minutes break between them.
People were friendly and open.
Some questions were easy, other were hard and seemed excessive for 1-hour session.
Interview questions [1]
Question 1
Design function which performs regex-like operation on a string.
Interviewer had a particular solution in mind that took a different approach from my own. My solution was algorithmically correct but not one that they were familiar with and preferred a non-closed form solution.
