Both candidates are in abundance. I know plenty of “engineers” who can’t do fizzbuz. I also know talented developers who can do fizzbuz for you in 60 seconds, but might not be able to invert your binary tree on a whiteboard in that amount of time. Neither of them are getting past today’s ultra picky interview-hazing rituals. One probably shouldn’t get hired while the other should. Companies seem to have a hard time distinguishing them.
