Right secondary school grades + near perfect exams -> Right Undergraduate
Right undergraduate + LeetCode (basically an exam) -> Big Tech job " + Case interview prep -> High paying entry level management consulting job " + Right connections -> High paying entry level wall-st job " + High LSAT -> Right Law School -> High-paying BigLaw job " + High MCAT -> Right Med School -> Right Residency -> High Paying Physician Job
If you notice, tech (Googles of the World and elite startups) have now fallen inline with the path for other white-shoe industries.
FWIW, I know at least a few people from memory that had non-technical undergraduates (usually economics) but are excellent at studying for exams. Sure enough, they did enough LeetCode they could get a job at Meta or similar. Ask them what actually happens in a CPU or similar technical question and you get a blank stare.

There are too many good candidates so you're having to... flog them harder?
God, tech hiring is weird. People in other sectors of the economy look at me like I've just announced that I have cancer, when I explain what the tech interview world looks like.
Programmers catch a lot of shit for being immature or unprofessional, but I think tech management deserves a harder look, when it comes to those things.
Thus, in lieu of a standardized framework we have to invent our own.
I very much agree though, the avg. CRUD shop could probably just ask Fizzbuzz and have the same outcome as these gauntlets.
The FAANGs and similar could easily have created such a thing, and driven wide adoption of it. They find some other value in their very-expensive process, or they'd have gotten rid of it with the snap of their fingers, if that were the only reason.
I suspect it's mainly to do with reducing turnover and, therefore, suppressing wages among their workers. Yes, despite those wages already being quite high. Wouldn't be the first time they've done it. "Solving" the problem would be trivial and relatively cheap, compared to the current processes, but it'd come at the cost of making it easier for employees to jump ship for more $$$, and none of them want that.
Why do the rest do it? Cargo-culting, mostly.
Where the hell did you go to school? When I did CS102, they were talking about linked lists and recursion. I would love to have seen device drivers, but when I was in school, everything was way more academic and impractical than that.
I am really curious to know what school has a cs 102 level class that teaches you writing a device driver?
I could perhaps see this as part of Operating systems class, where you just learned about how kernels works using a minimal OS (like xv6).
but that example you gave based on the expectation you mentioned are very extreme. This is why its hard to find talnet to hire.
None of the existing methods e.g. leetcode work well, so now we may resort to paid novel take homes e.g. write a simple device driver from scratch for the Intel E1000 in C99 over the weekend. Something you'd likely have been exposed to in CS102 type stuff.
