Dear talents, PLEASE don't waste your time on this company. Step 1: Call with HR Step 2: Hackerrank tasks Step 3: Online coding of a cache system Step 4: System design I've solved 3/3 tasks on hackerrank, then I successfully developed a cache system and I've answered ALL questions and covered ALL topics that were asked, and finally system design step. As a mobile developer applying for a mobile developer role, I was quite surprised that the discussion focused almost entirely on the server-side. Having experience conducting interviews myself, I understand that perspectives on system design may vary, and I recognize that the interview is designed to showcase the candidate's experience. While I welcome a challenge and fully support assessing knowledge across different domains, this particular approach will not effectively demonstrate the true skills of a mobile developer. Despite my best efforts to steer the conversation towards mobile-specific aspects and design considerations, the interviewer was primarily interested only in server-side implementation. Even when I emphasized my expertise in mobile development and suggested discussing the app's architecture or user experience, the conversation kept returning to server-side topics. I got rejected without feedback despite I've successfully passed all previous stages. The feedback I received only when I asked it myself and the feedback was "Don't afraid to go out of your zone comfort". The rest of the feedback is nonsense and not true. I shared this issue with HR and she answered that she is sorry that I had a bad experience. She had zero wish to understand the real problem. If you are reading this text I am sure that you are a great mobile developer, so please value your time and skills, Revolut will not do it. Also, you could read the latest articles where CEO specifies his new approach "Underperformers 'get six weeks to improve or must go'" P.S. Mobile development is not my zone of comfort, it is my specialization and the position's title ;)
