Data structures and algorithms were manipulated into a way to give IQ tests that can be studied for. Companies use these as hiring criteria and inflate the worth of memorized data structures and algorithms problems/knowledge. In short, they don't know it because mostly they don't need to, and there are obvious exceptions to that.
