Process
The interview was divided into three phases.
The first phase was with a recruiter, who asked me basic concepts such as SOLID, concurrency, the difference between a hash table and a hash map, and if I knew CQRS.
The second phase was a live coding exercise with a Revolut developer. They asked me to implement a URL shortening algorithm with increasing difficulty.
The final phase for me was a "technical conversation." I was asked to develop a bank transfer function, taking into account concurrency, locking, and isolation. Then, I had to translate the code to SQL. There were also some questions about microservices patterns.

Pros: 1. There are many real-world challenges to be solved with urgency.
2. You get to work on cool stuff from day one.
3. Many smart, competing colleagues.
4. The product is growing every day, so there are many new opportunities. There are even opportunities which are not yet polished, waiting to be discovered.
Cons: 1. Lack of internal technical documentation makes it a bit hard to navigate one's way through the huge codebase.
2. Not all teams use monitoring tools effectively, which may lead to delayed discovery of bugs.

Backend Software Engineer • Current Employee

Pros: A fast-growing and ambitious company with a dynamic and efficient work environment. Processes and bureaucratic hurdles are addressed promptly, which keeps things moving smoothly.
Compensation is competitive.
The engineering team stands out — highly skilled, collaborative, and genuinely supportive colleagues.
There are also good opportunities for internal mobility across teams and departments.
Cons: Some productivity metrics, like lines of code or PR count.
The culture favors those who prioritize work and seek big, complex challenges.
Industry-standard frameworks are rarely used, which may affect long-term skill relevance.
Compensation can be inconsistent — new mid-level hires might out-earn experienced seniors or leads.
Team quality varies: some have weak product direction.
It's easy to experience imposter syndrome, even as a strong engineer.
