11 technical interview rounds, plus a large take-home, and the company ends up stealing his work? Everything about this smells like the guy got scammed (assuming it's real).

Seriously, it's hard to think of a position that would be worth going through all of that even if it were legitimate.

Obviously it's fake, either a joke or misleading.

The only thing that's truly suspect is that the candidate was told their code was accepted into the codebase. I can't imagine this is terribly uncommon otherwise: it's more likely that it happens without the disclosure.

I can't tell if this is a joke or not. Is this a real email that someone received?
