I don't have any reason to believe he put it on his resume.

As for complexity, FizzBuzz is nothing like Hello World. Hello World only shows that one knows how to make a program compile/interpret and display fixed output. FizzBuzz demonstrates the above, plus an understanding of looping, basic arithmetic operations, and how to create program flow from that. Like it or not, that covers most of the actual coding requirements of probably 90% of jobs out there. It shouldn't be a deciding factor in getting hired, but it's an excellent first step in weeding out those who shouldn't be considered.

I recently interviewed a Ruby programmer, who was unable to write a Hello World in C, despite the fact he studied C and C++ in university.
