I applied online. The process took 2 weeks. I interviewed at MongoDB in Oct 2014
Interview
I was contacted by MongoDB recruiter after submitting resume through their website. I was set up with an initial call (HR Screen) and then phone interview with two engineers about a week after that. The phone interview had a coding component on a collaborative editing website. I was notified of rejection by a very nice voicemail message from the recruiter. Will apply again next year.

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.
