Friend of mine worked at Apple in the period between Jobs 1.0 and Jobs 2.0. He described an environment of management 'wolf packs' slowly destroying everything. Stuff like this, guy gets promoted as a manger of a group. Proceeds to force out current employees and replace them with his associates. Then abuse the review process to boost one of those to a higher position in the company. Playing the game right they all move up in 18 to 24 months. All fun and good except the groups they pass through are trashed in the process.
