> Interview processes also vary wildly—you can't really say that it works without defining 'it.' Are we talking multiple technical screens that require writing code or a single fluffy buzzword-laden conversation with a C-level? Both have failure modes, but those failure modes sure are different.

End of the day, everything evens out. People add the structure they need when they hire people. If your engineering interview process for some detail oriented gig is buzzword trivia with the CIO, the company will probably tank anyway. Conversely, if you do some nerd-fest whiteboard interview for a CTO in a bigger organization, you're probably not getting the right outcome either.
