I applied online. The process took 4 weeks. I interviewed at MongoDB (New York, NY) in Aug 2021
Interview
After the recruiter screen, there was a technical phone screen, and then a remote "onsite." The onsite consisted of five smaller interviews spread out over two days. The questions asked were tough but fair.
Everyone was pleasant to speak with and I was able to learn a lot about the working culture from the interview process.
Interview questions [1]
Question 1
Standard data structure questions with some additional twists. "How would you implement X data structure with Y new feature?"
I applied through a recruiter. I interviewed at MongoDB (Dublin, Dublin) in Mar 2026
Interview
Some behavioral questions and a rate limiter coding question with a staff engineer. They really wanted full proof code with no syntax errors and no interviewer guidance. Felt like the interviewer was not attentive.
Saw a fresh ad online, applied quickly and got a quick follow-up from recruiter. So far so good. Well, that's where it ends. After the recruiter call was scheduled, I got completely ghosted.
The interview process was seamless, and the recruiter was helpful and communicative throughout the process. The interviewers were friendly and knowledgeable. The interviews included DSA, Design, Concurrency, and Behavioural aspects. Had a great experience overall.
