This is not over-engineering. Defining a couple of functions to solve it would be over-engineering, like offloading Fizz to it's own function, Buzz to another one etc. Anything (deliberately) more is just comedy.

Training a neural network to solve fizzbuzz is over-engineering, fun over-engineering, but over-engineering none the less.

Depends on the position no? If you are looking for a developer sure. But if you are looking for an engineer, creative solutions are a plus.
