Senior Data Engineer Interview Experience - London, United Kingdom
Process
I applied online. The process took four weeks. It consisted of two interviews and a take-home assignment.
The first step was talking about the role, past experience, and other topics. The take-home assignment was some simple data processing in Scala, leaning into functional programming, and it was relatively straightforward. Next was a two-hour technical interview covering the assignment and talking about the platform. The interviewers showed some diagrams related to financial crime and asked for thoughts. There were more opportunities for questions about the role, the platform, and other topics. The interviewers were all very friendly, and it was an overall good experience. Having a good recruiter made things a whole lot easier, as the company has quite a complicated product, so coming up with relevant questions can be hard.

- 3.0Smart colleagues but stagnant company culture and cutsSenior Data Engineer • Current EmployeeLondon, EnglandAugust 26, 2026Pros: It is a fairly relaxed place of work with some genuinely clever people who are often the smartest people in the room.Cons: Company is desperate to IPO, they're cutting back on employee benefits, announcing an RTO mandate with 2 years notice to try and get people to jump ship, and genuinely feels like a place becoming stagnant. The sheer bloat of management is becoming obscene with new VPs added every few months for no discernible reason. They also have lost several really important technical individuals from the RnD department in recent years and aren't particularly motivated to keep talent. The RnD division has been faltering for a while, and despite spurious claims of doubled productivity there seems to be virtually no output or progress of that department.
