Revolut Software Engineer, Backend interview questions

In 2023 I passed 2 technical stages, but I failed at the third last stage, System Design, and I was given a detailed feedback which I appreciated. In 2024 I was approached by the recruiter and was asked to retry the last stage. I did System Design which in my opinion went much better then the first one, but I failed again. This time I didn't get any feedback. I asked 3 times, in 3 separate emails for feedback, which I finally received, but it was vague, lacked any technical details and it seemed to be AI-generated. In 2025 I was asked to repeat the process again by a recruiter, but I'm not going to take part in it because I had negative experience in 2024.
