Backend Engineer Interview Experience - Barcelona, Spain
August 16, 2026
Negative ExperienceNo Offer
Process
I applied through a recruiter. The process took 1 week.
An interviewer sends you an interface (in pseudo-code) that you need to implement and test. The implementation must support concurrent calls. AI usage is allowed.
The second part of the interview (last 10-15 minutes) are theoretical questions about various topics:
- database
- testing
- observability
- deployment
Questions
Implement banking interface so user can open an account and see the balance.
Extend the banking interface with deposit and withdraw methods.

Chaotic and toxic experience
Backend Engineer • Former Employee
London, England, United Kingdom
April 6, 2021
Pros: - Base salary is above average.
- If you are lucky, you are involved in interesting projects.
- Some microservices have been well designed and tested.
Cons: The overall culture in Revolut is at the same time chaotic and toxic. Once you join the organization, you are labeled as a "B player." On the first day, HR and your manager already put you under high pressure by saying that it's not for everyone to be promoted to "A player" by the end of the probationary period. If you fail, you are not going to be confirmed in the company.
You are evaluated on the basis of unrealistic KPIs decided by inexperienced managers who have been in the company long enough to be promoted. The company expects you to work 24/7 to accomplish these KPIs. So, expect to work 12-15 hours every day and during weekends with no extra pay for overtime hours.
Technical decisions are taken in a rush most of the time, taking shortcuts which can be risky.
This company pretends too much from yourself, and this has negatively affected my private life. I accepted the first offer on the table.

Backend Engineer • Former Employee

Pros: 1. You can gain some experience in the finance domain.
2. There are few good developers.
3. It's still good for your resume.
4. Stock options (but you can't sell them).
Cons: 1. Toxic culture.
2. Fairly incompetent management.
3. Unpaid constant overtimes. The company, of course, is saying something like, "We do not expect overtimes."
4. Broken, political-based promotion process.
5. CTO with his "interesting" ideas about system design. Moreover, he developed a trash framework and forces everyone to use it. He practices shaming of developers who have already left.
6. Low compensation (approximately 25% lower in comparison with the local market).
7. Limited tech stack – you will not be able to gain technical experience.
8. Normally at Revolut, management is treated as something more important than developers.
9. Managers force employees to leave a good review for the company on Glassdoor.
