This level of WAT reminds me of the stupidest interview candidate I've ever seen.
Interviewer: "You've mentioned for most of the interviews that you have libraries that can handle this or that. What'll you do once you don't have access to them any longer?"
Interviewee: "Oh, I was just going to bring them with!"
Interviewer, momentarily confused and speechless: "Like just make an unauthorized copy on a USB stick or something!?!"
Interviewee: "Yeah, exactly!"
He spent the next 30 MINUTES arguing with the interviewers (they were at lunch), and was *barred from re-entering the building* when they drove back. The whole of senior management freaked the fuck out and created a policy THAT DAY on how to handle an employee bringing in unauthorized code. (It's a MASSIVE copyright lawsuit risk if the company ships that in product!)
(My office-mate was at the lunch interview, hence me hearing the story. He came back looking like he'd seen into the abyss. XD I only saw the candidate walking sadly to his rental car through the window.)
And *no,* he left still not comprehending why this was a problem. D:
Obviously, properly licensed open-source code is different, but holy fucking shit was that not the case here.
