Well, I responded to uri who claimed it was the distinguish between wannabees
and serious coders. But in my book, being able to calculate the Nth Fibonnaci
number doesn't make you a serious coder. It just means you've past one hurdle,
and I will have some followup questions. You haven't failed the interview,
but you haven't shown that you're a serious coder yet.

But if I gave you a recursive formula (Fibonnaci or something similar), and
you show that you know how to calculate a generating functions, you do 
score bonus points. Extra points if you can even do the calculations in a
few minutes. Heck, I'd even give some points if you know what generating
functions are.
