      Senior Software Engineer Interview

      Negative experience
      Easy interview

      Application

      I applied online. I interviewed at Epsilon in Aug 2025

      Interview

      I interviewed for a Senior Software Engineer role. The process included a coding exercise and a system design task. Both were straightforward and I completed them in less than 15 minutes. The interviewers confirmed the solutions were correct. Since the interview was booked for 45 minutes, they kept circling back to the same questions just to fill time. Issues: • The exercises were far too easy for a senior role • Interviewers admitted the solutions were correct, yet they rejected me saying they needed a more senior developer • If being fast and accurate is not senior enough, then what exactly is? Finishing in 10 minutes instead of 15? • It felt like a box-ticking exercise rather than a serious senior-level evaluation Verdict: A waste of time. Do not expect meaningful challenges or fair evaluation here. The process is misaligned, and the feedback does not match the actual performance.
