Senior Java Developer Interview Experience - Warsaw, Masovian Voivodeship
Process
I had an intro call with a recruitment coordinator, and it went well. I was assured that Revolut has the best engineers.
I also had an overall idea of what to expect at the next stage. After that, I scheduled a live coding interview.
The company has lots of custom libraries and rewrites everything it can to ensure they have control over changes.
Questions
The company, for some reason, initially placed a strong accent on concurrency. I was asked to create a load balancer with production-like code. You won't be given any requirements initially, only to implement the register method.
I tried to clarify all requirements (target groups, health checks, etc.). From the interviewer's answers, I realized I shouldn't clarify requirements at this point.
More requirements will be added, like capacity limitation and uniqueness checks.
- Why do you prefer
register(String url)overregister(URL url)? - In what case will an ArrayList append not be constant time?
- Why is it not ready for production (concurrency)? What problems do you see? What's the simplest way to fix it?
I didn't receive any feedback, so it's hard to tell what was expected.

Revolut Work Experiences
- 5.0Great Team, Development, And PaySenior Java Developer • Current EmployeePoland, Maine, United StatesJuly 10, 2024Pros: environment, team, development, salary, benefitsCons: Actually, there is nothing to complain about.
- 3.0Good Pay, Boring TasksSenior Java Developer • Current EmployeeDubai, United Arab EmiratesMay 23, 2024Pros: High salary Remote work Nice and smart colleaguesCons: Boring tasks (it depends on the team) Big monolith Inadequate management expectations
- 2.0Smart Colleagues, Bureaucratic HellSenior Java Developer • Current EmployeeDubai, Dubai, United Arab EmiratesDecember 19, 2022Pros: Good compensation. Remote work. Smart people (depends on the team/department).Cons: HR processes are not transparent at all. The bureaucracy that was recently introduced is inefficient (random salary benchmarks, relocation is a pain). Performance review is absolutely subjective. The only way to get promoted is to connect to your LM. Nepotism over professionalism. Retail department is hell. Chaotic approach. Big tech debt, but management wants to keep expanding. As the result, even trivial change takes forever. Mono-repository, good luck with waiting hours to run some tests. High people turnover in the last 2 years. I saw lots of people leave because either they got bored, or they couldn't negotiate salary/relocation. As the result, there are many places with code that is not owned by anyone, that is hard to maintain. In-house solution that doesn't work (ES). Depending on the team - long hours. You have to protect yourself from it, otherwise, there would be many people who would want to use you without additional pay. KPIs between teams/departments are not synchronized. Sometimes they even work against each other. Teams are gathered from different locations. On the one hand, this may be a good opportunity for you to join any team, but on the other hand, there is no way when you can choose a team that is based in a certain location. Therefore, you cannot be in the same time zone and meet with your teammates in the office.
