I applied through a staffing agency. The process took 2 weeks. I interviewed at MongoDB (New York, NY) in Sept 2021
Interview
Applied through the recruitment firm. Process described included 1 hr technical phone/zoom screen and 4 hr onsite interview. I didn't make it past the technical screen itself, so can't comment on onsite experience.
The technical screen question was a LC hard question, and I honestly didn't expect that during a tech screen. I was only able to provide half working solution and explain my though process on how to solve it. But that wasn't sufficient for me to move on to onsite.
If you are applying be prepared to answer LC hard questions (even during tech screen)
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.
