      Senior Software Engineer Interview

      Jul 17, 2025
      Anonymous Interview Candidate
      No offer
      Positive experience
      Average interview

      Application

      I applied online. The process took 2 months. I interviewed at MongoDB

      Interview

      There was a bit of confusion in the beginning because I got an automated rejection shortly after speaking with the recruiter but that ended up being a mistake. Other than that the process was pretty streamlined (nice interview portal), although there was a lot of time in between interviews. Interview questions were pretty standard.

      Average interview

      Application

      I applied through a recruiter. I interviewed at MongoDB in Jun 2026

      Interview

      The interview process was well organized and flowed smoothly. However, it had quite a few stages, starting with an HR interview to assess my background and skills, followed by a technical interview that included a live coding exercise and several in-depth technical questions. Overall, it was a thorough process that effectively evaluated both technical ability and problem-solving skills.

      Answer question

      Question 2

      I interviewed at MongoDB

      Interview

      Interviewer had a particular solution in mind that took a different approach from my own. My solution was algorithmically correct but not one that they were familiar with and preferred a non-closed form solution.
