I applied online. I interviewed at MongoDB in Apr 2023
Interview
Recruiter screening interview, then coding interview, then Director Interview. Followed by coding interview, VP interview, design interview and domain specific knowledge interview. The entire process was a bit long, but I felt that everyone was very approachable and the questions were very fair. I prepared for all the hard stuff but sadly with blinders and overlooked the easy questions, and this was where i tripped up.
Interview questions [1]
Question 1
Both coding interviews involved trees. The design interview related to something I've already done, and the domain specific interview.. well, google all the obvious stuff :D
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.

I applied through a recruiter. I interviewed at MongoDB
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

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.
