      Senior Software Engineer Interview

      1 June 2026
      Anonymous employee
      London, England
      Accepted offer
      Positive experience
      Average interview

      Application

      I interviewed at Synthesia (London, England) in Mar 2026

      Interview

      The interview process was clear and efficient. It was a 4 step sequential loop, which is a lot nicer in my opinion than 1 day with 4 interviews as it gives you enough time to prepare for each individual interview. The 4 interviews were: * Hiring Manager with standard questions around ways of working, dealing with project deadlines, etc. * Coding/Problem solving that allowed use of AI to aid with coding and so it felt like there was enough time to get the ask done. * System Design interview was more structured than a typical open ended system design, but that helped break down the interview into smaller achievable designs. * Leadership interview: This was similar to a normal behavioural interview, but more focused on ways of working, and how you deal with projects and problems end to end. Generally i thought it was a well structured interview loop, that allowed enough preparation.

      Question 1

      There's a decent amount of focus on dealing with customer/stakeholder needs in your examples in the behavioural interviews.
