Debug team? Would that be the same thing as game testers? (Game testers being people who meticulously play games for hours on end, looking for any problems that haven't yet been found or worked out.)
I was given a personal tour of Nintendo of America's Redmond campus. At one point during it, I passed a hallway that led to the game testers' area. My guide said we couldn’t go down it -- even he wasn't allowed in there. It was closed to those who are hired to spend perhaps eight hours each day playing one level of one game (this may be an exaggeration), looking for bugs.
Being a game tester is dreary work, but it is also elite (because it means special access, at least at Nintendo). Thus it is a rather paradoxical job.
