Revolut Python Software Engineer interview questions

Overall process is around 5 steps. 3 of them are technical (Live Coding, Technical Conversation, Systems Design). They're quite well structured and they give you some information to prepare them in advance.

Applied for a Python Software Engineer role. What followed was one of the most unprofessional interview processes I've experienced. The initial screening invite was completely empty - no job details, no requirements, nothing about what to expect. Should have been my first warning. Screening call: - Interviewer showed up late, then rushed through everything - Cut me off constantly, wouldn't let me finish a single answer - Asked random technical questions with zero context - When I asked about the role or team, got nothing back - Felt more like an interrogation than a conversation Technical round: If you look online, you'll see they ask the same 3 questions to everyone: URL shortener, load balancer, or ledger system. They gave me the URL shortener - pretty telling about their "technical innovation." Still crushed it though - finished early, wrote full test coverage, used proper design patterns (SOLID principles, strategy pattern), even added multi-threading with locks since they emphasized concurrency. Answered every question they threw at me. Then got a generic rejection saying I lacked "specific knowledge." What specific knowledge? They never said. Tried to get actual feedback multiple times. Got an automated email I couldn't even reply to. Asked specific questions about what went wrong - complete silence. Save yourself the time. This isn't how serious companies run their hiring process.
