I mean, he called the other engineers "those fuckers." I was definitely not sympathetic. I was pretty livid, however, context is necessary.

This person didn't even try. Engineers at this company rarely ask for help from other teams or collaborate. Management has talked the talked, but there is no walk to actually take down these silos. I pointed him at product and BA people that offered to help, but he didn't ask them, either. Instead, he thought he could reverse engineer it, which probably took 3x longer than it should.
