Maybe we just see it differently, but I’d consider everything you’ve listed as exactly the sort of stuff that just gets memorized. I don’t even think the breadth of what you listed is that bad actually. Especially for recent grad brogrammer types with no serious life obligation time commitments, memorizing an entire program of study like that is probably only an investment of ~1 month of time, and has practically no correlation to on the job effectiveness once hired.

I’m speaking from ~10 years of experience running my team’s recruiting in a quant finance firm, where many interview requirements / tests / etc., came down from executive managers, so I got to see a wide range of performance on tests of all sorts, riddles, hardcore algo trivia, etc.

The sum total of all that leads me to believe quite strongly that the best signal to noise comes from super careful and tedious resume selection followed by conversational and behavioral interviews that recursively probe into more specific technical details.
