And yet unstructured interviewing basically works and the world keeps spinning. If 'random' truly was a better result (as the article suggests), then in a hiring round for a programmer last year, we might have discarded our candidate that won and is awesome for the one that couldn't conceptually 'get' FizzBuzz.
