ohh come on. Nobody ever needed Fibonacci or Factorial for anything, but if you bomb those after a few clarifying questions (like not knowing the initial values of fib or it's definition) I'm not sorry.

Factorial is just a for loop and with Fibonacci you might want to talk a bit about recursion and caching. That's it.

Things like these are rote memorized solutions that fill what could otherwise be useful problem solving or software knowledge space in my brain.

They're dumb.

Then don't memorize. I'm OP and as I said I give the solution, candidate only has to code. Like I would with FizzBuzz.

People still fail.
