A recruiter contacted me, we had a brief call about my background and Revolut in general. After that, I got a one-week coding challenge in Java. I successfully proceded to the next round. The next round was a phone interview. I've expected more algorithmic (problem-solving) type of interview, but the interview was really technically oriented. For 2 hours interviewers were asking questions about Java, concurrency, multithreading, databases, transaction isolation ... At the end of the interview, they asked a very easy coding question. The purpose of this question was not to determine problem-solving abilities, but rather java knowledge. After that, I got feedback that they are looking for someone with more experience in Java. All in all, communication with the recruiter was very pleasant. The phone interview was good, but I was not prepared for that type of interview.
