Sadly "yes". That said, it's not "so hard" in absolute terms, but that is precisely why it works so well as a zero'th order filter.
You wouldn't want to hire based on passing that, but you certainly want to NOT hire based on failing. (Depending on what you're hiring for, of course; I can't see not taking a sales guy to do sales if he couldn't do it.)
