Thorough. Revolut wants to make sure they find the right fit skills-wise, but also someone who will fit from a cultural perspective. Questions were direct and specific, and I felt that my interviewers were curious to get to know me (as a human) throughout the process. The process started with a take-home analytics problem, followed by a few rounds of interviews with increasingly-senior Revolut team members. I received immediate feedback after each round, typically hearing back on next steps within 24 hours of each interview - a welcome contrast to some of the other interview processes I have been going through, and one of the things that attracted me to the company.
