      Staff Software Engineer Interview

      8 June 2023
      Anonymous interview candidate
      No offer
      Negative experience
      Difficult interview

      Application

      I applied online. The process took 4 weeks. I interviewed at Mozilla in May 2023

      Interview

      Had a call with a recruiter, a technical screening, a behavioural interview with the engineering manager than a take home assignment where things went down hill. Everyone I talked to with great, got the impression that they have a great engineering culture, but unfortunately that was not reflected in the take home assessment, which was one of these leetcode brainteaser kind of questions t hat has nothing to do with the skills required on the real job as their actual repo was using react & redux. These leetcode kinds of questions only test whether a candidate has studied for these specific kinds of questions, has seen them before and can memorize the answer or not, or if they googled / chatgpt'd the answer, they're a terrible way to assess a candidate's skills as someone just out of school without any real skills or experience who spent time studying for them could pass them, and people with 10+ years of experience shipping multiple projects with a wide range of technologies wouldn't.

      Interview questions [1]

      Question 1

      Typical behavioral questions: like previous projects, navigating conflicts, how teammates would describe you, etc..
