One of the side-effects of the technology crowd becoming saturated with the straight-laced, standardized-test oriented, topper types is that LeetCode aligns neatly with how you prepare.

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.
