Yeah. To be honest, there are cases where I've been that guy.

But past a certain level, it's your job to explain your own weaknesses too. I just had a technical interview the other week and they relied way too much on definitions and whether I'd heard of this and that. I happen to do great at those but I want to be sure I can be productive (the position uses Elixir, which I'm totally unfamiliar with) so I'm suggesting they give me a take-home exam.
