I think it is fortunate that great engineers like OP are rejected in Leetcode style interviews. The benefit is twofold:

- It makes fresh graduate noobs (or even just noobs in general) able to compete on equal ground on high-paying job prospects. Think about it, if every high paying jobs out there value experience over leetcode style of interviews, then young noob programmers won't be able to rake great salary because all of those jobs are filled already by experienced engineers

- Great engineers should just use their talent somewhere else in startups, create more innovation, create more wealth rather than helping the big tech giants become bigger
