When I interviewed for a coding job about 15 years ago I was asked to talk the interviewer through some code. Nothing very exciting, just a very basic loop.
It turned out that 3/4 of the people applying for the job _could not code at all_. They weren't just bad coders - they had never coded anything in their lives.
I find that to be exactly true. The really surprising thing is that a college degree or experience at a big company doesn't necessarily tell you what you can learn from just walking through some very basic code.

It's _those_ people that FizzBuzz catches out.
