Difficult Interview

I applied online. The process took 3 weeks. I interviewed at MongoDB in Jun 2022


The process was comprised of 2 parts. Initially, a call with the recruiter, a call with one of the hiring managers, and a coding assessment. After proceeding through this stage, the final stage (essentially the on-site, but online), involved two behavioral interviews, a design interview, and finally a pair programming interview. This interview process presented a great opportunity to meet all of the members of the team and it was extremely reassuring to find that all the interviewers (prospective colleagues) were very welcoming and comfortable answering any questions I had. My recruiter, Ronan, checked in with me regularly throughout the process and provided concise documents detailing how I should approach each interview. Overall, the interview process was challenging, but very well structured and flexible, and gave a great insight into the positive working culture that has been cultivated at MongoDB.

Interview Questions
  • Some standard behavioral questions: - "Why are you looking to leave your current role?" - "Why MongoDB?" - "What is your proudest accomplishment in your career?"
