It sucks when you can tell that a personality mismatch is causing the interviewer think you don't know what you're talking about. Or they could just be an arrogant ass, who knows (that if/else thing certainly raises the possibility). About the offer you got, maybe they thought you were strong in areas that would be important to the DW team even though you didn't fit into their expectations for the position you interviewed for. I've interviewed people who were obviously talented engineers but not quite right for the position in question, and suggested them for other positions they were better-suited for. This has worked well in my experience, but who knows if that's what happened at Netflix.
