Not the OP, but from a certain point on (I'd say 3-5 years into one's career, I'd say maybe even earlier) school-type tests become quite ridiculous, as in real-life programming/development has nothing to do with how people are graded in school.
If by "nothing to do with" you mean "uncorrelated", then this is very trivial and empirically untrue. There are a lot of tests that correlate with peer and manager-rated performance in software development (and many other roles).
Even the dumbest most ad hoc unrelated tests will have nonzero correlations, and the well-studied principled ones much more so.
The better argument is that tests are high effort and can feel demeaning. But it's not productive to pretend they don't work.
