I’m not for or against these leetcode style tests, but I think the difference is that they see a correlation between admission test score and how well they’d actually do on the course. Can the companies using “leetcode” tests prove the same?
A common thing I see missed in arguments against like leetcode is that good hiring pipelines would not look at just leetcode scores. You want leetcode + good project + system design. Leetcode is excellent for testing data structures and algorithms, reasoning about code and edge case etc. These are absolutely necessary but not sufficient to build good software.
