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.

It was an amazing experience I'm just gutted I didn't get the job! The team of superorganized and I was really impressed with the process from start to finish. I would like to see a bit less time spent on the process.
