I applied through a recruiter. I interviewed at Revolut (Barcelona) in Jan 2025
Interview
The interview process had 4 steps:
1. Short call with a recruiter where they ask why you applied for this job and why Revolut and also explained the job, interviewing process etc,
2. Live coding interview with a SWE.
3. Interview with a SWE where they ask about DBs, concurrency, etc.
4. Behavioural interview.
Interview questions [1]
Question 1
At the step 2. of the interview process they ask me to built a simple load-balancer in any programming language (I choose Java) and also test my solution. They focus on coding fast and having a quality solution, meaning it is well tested.
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.
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.

Question 1
Design Revolut Stays. Hotel info comes from an external partner. Bookings must be done through the external partner as well.
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
