You are making amazingly far-reaching decisions from very limited information, a quality I definitely wouldn't want to see in my superior. A dislike of a certain test must mean "to destroy some workplace". I am now wondering if all the issues we see with politics lately are happening because people are becoming single-dimensional, unable to even consider someone else's view if the way it's presented slightly deviates from what they demand.

As somebody who was often interviewing other people fighting for jobs at top companies I worked for, I would never ever offend them by throwing FizzBuzz in their faces; I don't have such arrogance in me. I would rather try to figure out what clicks with them and throw them something tasty where they can show off, then increase pressure to see what needs more work, then explain/discuss what could have been improved. I would respect their time and help them to learn something on that single interview they had with me. Never throw into their faces that they are frauds which is implied by employing FizzBuzz. One doesn't have to be a super psychologist, just simple empathy is sufficient to understand that people perform best when they are respected and treated as adults.
