I applied through an employee referral. The process took 3 days. I interviewed at MongoDB (Dublin, Dublin) in Aug 2021
Interview
Mutual and respectful. Very engaging, and friendly indeed. I had to introduce myself and talk about my experience. This went on for 30 minutes, then in the final 30 minutes I was supposed to solve the question asked.
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.
