I applied through a recruiter. I interviewed at MongoDB (Dublin, Dublin) in Apr 2025
Interview
I first got an HR interview with an amazing recruiter - she asked about me, my college background and some projects that I had built. After that, you get a Karat interview with 2 questions - they really like string questions and it is all live coding.
Other Software Engineer(Internship) interview reviews for MongoDB
First had a phone call with a recruiter, then a technical assessment through a third party (with a person, not one of those websites), and then a three hour interview with three members of the team. Two of the three hour segments were coding, and the other was a behavioral.
