I applied through a recruiter. The process took 4 weeks. I interviewed at Revolut in Jan 2025
Interview
The interview process consists of several stages,
- screening interview with recruiter, with some basic technical questions
- live coding interview, solve a simple problem using best practices, focused on overall code quality and test coverage
- technical conversation, brief live coding and then technical discussion, focused on concurrency and databases
- system design interview, designing a system related to Revolut's domain
Overall, the interviews were challenging but also very interesting. The interviewers were all very professional and polite, asking challenging but fair questions.
The process is time consuming and involves adequate preparation, but it's also a good opportunity to learn and engage with very talented engineers.
Interview questions [1]
Question 1
One example from each stage
- explain the CAP theorem
- how would you test a method that returns a random value?
- what's the difference between optimistic and pessimistic locking?
- how do you handle transactions involving multiple services?
Very kind. The questions weren’t easy, but with knowledge of database configurations, concurrency, locks, and some practical experience, you are able to answer them clearly, confidently, and effectively overall. It was good time.
Recruiter round, they’re basically looking for buzz words. They asked for my experiences in handling different scenarios, then other db and concurrent related questions . Overall it was straightforward, just go through other’s experiences here and you should be covered

Question 1
Concurrency
Optimistic vs pessimistic locking
Db isolation levels
HR interview, coding interview, then system design interview. No specific feedback from them. I really thought I went well and answered everything at least reasonably, but didn't get an offer.
