First, I had a meeting with a recruiter. She was very nice and helpful. It lasted around 15 minutes, discussing my past experiences and so on.
First code interview: Approximately one hour with a Revolut engineer (and I think a shadow interviewer, but I don't remember 100%). It focused on solving a few problems related to a URL shortener. The problems themselves were not difficult, but you were expected to write tests, good code, etc. At times, the interviewer would ask you to explain your choices, discuss alternative approaches, and identify potential issues with your solution. At the end, there was about 10 minutes for technical questions, such as why you would store data in a hash table and the time/space complexity of certain operations. Finally, there was reserved time to ask the interviewers any questions.
Second code interview: Two Revolut engineers and a shadow interviewer. Approximately 1 hour and 15 minutes. The task was to solve a basic bank transfer service. As before, the interviewers asked about my thought process, issues, etc. After writing the code, we moved on to technical questions. They emphasized concurrency and locking, which was supposed to take about 15 minutes but stretched to around 30 minutes. At the end, there was reserved time to ask the interviewers any questions.
Finally, I met with my prospective team manager and the backend lead. This was a more informal meeting, focusing on my experience and sharing details about the team's day-to-day activities.
All in all, it was a very good interview experience.
Questions on concurrency, locking, pessimistic/optimistic locking, etc.
