FWIW, I have come across examples in the wild of engineers who were extraordinarily polished and facile at everything leetcode, and poor at computer science. Not many, but some. This is a somewhat recent phenomenon.
Best tests are simple and common computer science problems in algorithms and data structures with no tractable solutions. There is no facile answer, you truly have to reason from first principles for any particular scenario because there is no alternative.
