      Senior Full Stack Developer Interview

      17 May 2026
      Anonymous interview candidate
      Hamburg
      No offer
      Negative experience
      Difficult interview

      Application

      I applied through other source. I interviewed at cofenster (Hamburg) in Jan 2026

      Interview

      Process took 2 months. Had an initial interview with Head of Engineering then a live coding challenge. Challenge was frontend and backend, AI was not allowed, it was initially set for 1 hour and a half, but in the middle of the session they expressed that all the interviewers were taking over 2.5 hours. That means that they were not realistic with the challenge and even with evidence they didn't improve on that. They also ghost interviewers when post-challenge feedback is asked.

      Interview questions [1]

      Question 1

      Implement a routing mechanism in React and a batch loader mechanism in NodeJS + GraphQL.
