I see Microsoft is one of the alleged participants, perhaps we can call them the Billforce.
I wonder if small companies are allowed them, I can think of plenty of tasks I would be ashamed to give to genuine employees but happy to give to Gordon's Gofers, and they probably would learn something, in a sense.
Of course, this gives the lie to the absurd 'we need more science / engineering graduates' meme. Which we don't. We need a business / societal culture in which we can make use of more science / engineering graduates but that's another thing completely. (Want a new nuclear power station, phone up Aviva and order one, you don't need Ph. D. research. You will find there's a 10 year waiting list for pressure vessels but that, too, is another thing [assuming this much repeated factoid is true]).
