What percentage of what you do as a software engineer has direct linkage to computer science?
My guess for most of us is "not very much at all", several of the best people I've worked with as programmers did not have a CS degree, and I've interviewed people with CS degrees who could not write a function to sum an array of integers in any language of their choosing, meaning "honoring their degree" would have been an unwise choice.
What does solving random puzzles from Leetcode have to do with day-to-day engineering work? IMHO, the emphasis should be on previous experience, CS domain knowledge and systems architecture / design. Maybe degrees need to be fixed to convey more useful knowledge...
