Revolut Software Engineer interview questions

I interviewed in Revolut in end of August 2025 and process took 2 month (first interview - acceptance of offer). It can be shorter for some people but I tried to have max time I can between interview stages. Recruiter informed me about all the stages I will go through and we also had catch-up calls before each interview stage. That helped me a lot tbh. Stage 1, Screening; Recruiter asks simple questions, questions asked in every company Stage 2, Live coding; Simple coding assignment with TDD. I used Spock but you can use any framework you want. I covered all possible cases but asked how can I tests a function which returns random values. I got stuck on that one but interviewer gave me hint that resulted me answering question correctly. Stage 3, Tech; I has 2 sections. First one is live in Java coding again without tests & writing same business logic in SQL in a thread safe way. In the other half interviewer asked questions about concurrency, thread safety, DB transactions & management, microservices and etc. Stage 4, System design; I have given a task to draw system architecture design for a system in Banking domain. Interviewer also asked to write down table structure for this system. After passing all these stages you are accepted as SWE but they have one more stage where you matched with teams that looking for developers. After this meeting they can hire or not hire you based on those teams' feedback about you.

The process begins with an automated Online Assessment (OA), followed by a meeting with HR where you learn more about the hiring process and the upcoming steps. After the HR meeting, the next stage is a live technical interview.
