Apple is either clueless or is having serious problems maintaining competent hardware engineers despite them being the second wealthiest corporation in human history and sitting on a massive war chest. Instead of hiring the talent they need, obscene bonuses are delivered to executives since Jobs died.
The question is, why are they having trouble finding designers? I have heard various accounts from people, as well as rumors, that their pay is below industry standards. Also, certain jobs are not stable with Apple hiring people for consultant like specialized positions at employee wages, tying them to insidious contracts, and then dismissing them when their niche skills are no longer needed. It is also reported to be an abusive place to work where employees are belittled and insulted and their contributions not acknowledged.
