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.
