Philosophy students tend to be understandably insecure about the value and prestige of their field, and study often ends up indirectly training students to defend philosophy. Impressive-sounding pontificating, problematizing, cranking out arguments and fallacies and refutations, deploying jargon and historical references. There's a whole toolkit used to dazzle, bewilder, and cow the untrained. Not to mention outright self-promotion, like Chalmers in this article: oh yeah these companies totally desperately need more philosophy graduates!

It's great preparation for law school, as a commenter has already pointed out, since skill in one game carries over to the other. The value of philosophy outside a self-referential intellectual game is extremely dubious, and I think one can reasonably argue that philosophical training does more harm than good by inculcating bizarre/narrow/counterproductive intellectual habits/commitments/bugaboos. But philosophers have tricked themselves into places where they really have no business being, like hospital ethics panels. Cool for these guys though, it seems harmless.
