Revolut Software Engineer interview questions

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.

There was a quick phone screening and I've got the code test. They said it can be taken as long as you need. The test was quite tough. They set the test to use all of their skill what they are using on their project.
