Pros
There is no "busy-work" at Apple. Everything is done for very good reasons -- there is no wasted work. You're proud of what you do, and people you meet outside of Apple really care about what you do.
Cons
Potentially long hours. Long lines at the cafeteria? But other than that, there's no apparent downside of working at Apple.
Advice to Senior Management
The senior management team at Apple is the strongest in the industry. They have experience, vision, unyielding innovation, and the power to execute.
