I feel your pain. One thing I would suggest is that programming/software engineering is a broad church. Not everything is large scale backend work. I personally get a lot of satisfaction out of frontend development, and the expectations there seem to be a lot less about hypothetical google-scale nonsense that will never happen in the role, and more "do you know the tech?". Despite what people say/think modern JavaScript/typescript is good to work with and in modern web apps that are 10s of thousands of lines of code there is often a surprising amount of actual "engineering" required. That said, sometimes just knowing some of the basics might be enough compared to other candidates. E.g. for the tweets in 3 seconds thing, you could talk a lot about horizontal Vs vertical scale and what might mean etc etc and go from there rather than a "sorry I have no idea". You don't always need to be "correct" but just show you are aware of the hypothetical solutions to their hypothetical questions. Good luck. Hang on in there. I appreciate this can be high stakes for tou, while posting an answer here in a comment is zero stakes.
