I am with the blog poster here - fuck you and your coding test.
I lowered myself to do one recently, we walked through it in the next stage interview, where it became apparent the " tech leads" were incompetent muppets, who were intimidated when they saw a better solution then they had as their "approved" answer. Walking through slowly with them why their solution had poorer performance at both low and high volume, I was left with the distinct impression that the vast majority of the incompetent devs who would fail fizzbuzz are somehow doing the hiring.
Scary times!
