Binance Senior Backend Engineer-Java interview questions

A call with the recruiter(Elena, who was very professional and friendly), and a 3 stage technical one, the first being a generic algorithmic interview, the second a system design interview, not sure what the last one is. I failed the system design one, with no useful feedback. My solution was reasonable but had some unknowns that I did highlight. Although I have designed similar systems in the past, I always struggle with such interviews, mainly because in real life you don't get 45 minutes to design a KYC system.
