It's easy to imagine that smart people's thought processes are imprisoned by their own egos. It is an easy trap for a smart person to fall into. Algorithmic testing has real practical implication if the role requires it, which a subset of the engineers at the aforementioned companies will use. The other practical implication is standardization of the interview process, rooted around an academic background in computer science. It's easy to test whether someone knows a "fundamental" (whether it's actually fundamental to the job is another question) cs data structure or algorithm. The idea is, interview for square pegs, since it is easier to measure the quality of that particular shape at scale. If there is a high-quality peg that happens not to be a square, it is a loss that the system is willing to accept, provided that a large enough % of the good candidates are squares.
