I applied online. The process took 1+ week. I interviewed at MongoDB
Interview
Phone screening:
interviewer asks questions about resume. She seemed to only say yes to any of my descriptions, neither agreeing nor discussing why. I asked for feedback on my interview to no avail. Hopefully, they can start doing a better job on interviewing. I heard they ask brain teasers which can be quite a turnoff for many interviewees
Interview questions [1]
Question 1
She didn't ask any technical questions. Only behavioral questions. Seems they want someone familiar with their product and who can hit the ground running.
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.
