That's a disingenuous take. It's extremely unlikely you'll get asked any of these specific questions, but very likely you'll be asked something in the general space.

Core knowledge extrapolates... to learn system design, one studies the design of "solved" systems, thus learning to solve for new design problems.

If a company is asking leetcode questions verbatim, they probably don't care so much about that part of the interview anyway

i have been a software engineer for 20 years and never had to implement any of this stuff myself in my career. the last time i did was in my master’s program in CS. in contrast i’ve had to implement custom memory allocators and many other non trivial algorithms which cannot be implemented in 10 minutes but take days to design and implement.
