I learned to program on the job, I have masters in economic (econometrics focused, which I was hired), but I am not sure how someone can't make there way through FizzBuzz. I am sure mine wouldn't be the best code written, particularly during an interview, but I could make it through the test. Based on my experience as an air traffic controller which requires more tests than I care to state, when we would transfer facilities we were given oral tests to gauge our experience. We would mark down the areas deficient that needed review and check areas off where knowledge was deemed satisfactory. There would be zero air traffic controllers if we dismissed candidates answering one question wrong regardless of simplicity.
