      Senior Software Engineer Interview

      6 Aug 2020
      Anonymous employee
      Austin, TX
      Accepted offer
      Positive experience
      Difficult interview

      Application

      I applied online. I interviewed at MongoDB (Austin, TX) in Jan 2020

      Interview

      Phone call with recruiter. This is helpful to learn as much as possible about the position and the company. Phone technical interview ~45min This is a classic coding exercise via phone and shared code editor. Usually not incredibly hard but challenging enough to filter out non qualifying candidates. In-Person interview ~3h This includes a coding task, an algorithm challenge and a system design challenge. You also have enough time to chat with the hiring manager and director to get a better idea of what the position entails and any career opportunities. The technical interview was challenging and I really appreciated that most questions were coming from day to day work and were not obscure tasks. Everybody was very easy to speak with which gave me a good insight on who I would be working with. I got a response the day after the interview, the recruiter really helped me navigate the offer. I took the offer and moved to Austin within a month although they were ready to give e more time to adjust.

      Interview questions [3]

      Question 1

      Coding question related to working with some recursive data structures. An actual task from day to day work.
