It's really hard because I've failed interviews by pitching "ok we start with postgres, and when that starts to fall over we throw more hardware at it, then when that fails we throw read replicas in, then we IPO, then we can spend all our money and time doing distributed system stuff". Whereas the "right answer" (I had a man on the inside) was to describe some wild tall and wide event based distributed system. For some nominal request volume that was nowhere near the limits of postgres. And they didn't even care if you solved the actual hard distributed system problems that would arise like distributed transactions etc. Anyway, I said I failed the interview, really they failed my filter because if they want me to ignore pragmaticism and blindly regurgitate a YouTube video on "system design" FAANG interview prep, then I don't want to work there anyway.
