Oh, I guess a few of these additional rules might prove helpful for weeding out people who just memorized FizzBuzz but don't know much more.

However, all of these "don't use the right tools" and "write extremely compact code" rules mostly select for people who are good in code golf, not for people who can solve actual business problems or write maintainable software.

And it seems like this was the only programming challenge in the whole interview?!

This is my takeaway, like maybe 3 extra rules would be worthwhile but by god there is too many, what are you learning here for something so simple as fizzbuzz
