      Software Engineer Interview

      2 Dec 2025
      Anonymous employee
      London, England
      Accepted offer
      Positive experience
      Average interview

      Application

      I applied through a recruiter. The process took 3 weeks. I interviewed at Heron Data (London, England) in Oct 2025

      Interview

      It was a clear interview process with 3 stages: 1. Initial chat (20 mins) - Just to understand motivations around moving roles and what you're looking for in your next role 2. A PR review style interview (1 hour) - I worked with one other interviewer on a PR to talk through good things and improvements, and then spent a bit of time adding to the PR 3. Final round broken down into 4 ~45 minute interviews. The first two focussed on system design and looking into the design of a previous project, one was a more culture fit style interview and finally a chat with someone from the C-Suite. All interviewers were super friendly and communication and coordination throughout the process was extremely clear! The process seemed to mimic what the actual work environment would be like which I really enjoyed - didn't feel like I needed to jump through hundreds of hoops or leetcode problems to succeed.
