I applied through a recruiter. The process took 2 weeks. I interviewed at MongoDB in Aug 2020
Interview
Cold contacted by a recruiter. Had an initial screen with recruiter to discuss background and interests, then had an initial coding screening using coderpad, which I failed.
Question asked was unusually difficult for an initial screening, seemed like you either have an aha moment and get it, or you fail. It also didn't seem to relate to what kind of work the team actually did (core infrastructure work but asking you to invent a novel algorithm on the spot under interview pressure).
Interview questions [1]
Question 1
Design and code an algorithm to randomly generate mazes for a children's book.
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.

Interview
Process was: Recruiter screening, Phone Screen, 5 Virtual Onsite. The whole process took a long time. I loved each interviewer, they were really friendly, nice and passionate with their work. The interview questions were unique and on the harder side but well organized.
I applied online. The process took 3 weeks. I interviewed at MongoDB in Oct 2025
Interview
Recruiter phone interview, a technical screen, then multiple technical interview rounds. I've gone through non-concurrent programming, concurrent programming, algorithms and the design one; didn't make it to the behaviorial and final interviews,
The process is well explained, and I have even got feedback afterwards.
