I've lived this. Myself and a very expensive team of EY kids were waiting eagerly every day for anyone in corp management to throw us any kind of tasks.
On the rare occasion that we were given a task, we would all descend upon one computer like vultures, group-solving the problem typically in 60minutes or less. Then it was back to doing nothing.
Diplomacy (the game) became our primary activity. It was fun, but such a terrible waste of time, talent, and money.
