Prestige is a euphemism for "not worth it," as it's what they offer instead of paying you. Ask yourself, "do I admire these people and do I want to be like them?" If the answer is not an enthusiastic hell yes, they're time vampires, get the hell out.

Know who is attracted to prestige? People who don't have something that comes free with success. They make up the long tail of the distribution, and they're not first movers, risk takers, or leaders. If it's already prestigious, it's mostly played out.
