I applied through a recruiter. I interviewed at MongoDB (New York, NY)
Interview
1. Recruiter Interview - about a 30 min phone convo about the roles and interview expectations etc
2. 1 hour techincal interview - Had to code a Trie structure that I did except I made a char array instead of Trie array. I corrected myself after running
I did not get through to the next round as they said the ramp up time for me seemed more than the other candidate
Interview questions [1]
Question 1
Build a Trie Structure since they want something to add word, check if the word matches to a inputted word, & see if word starts with the same letters
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.
