Avantages
Working at Apple means you get to work on some of the coolest products. These are products that people really love. The structure is quite flat, so you will routinely find yourself in a meeting with engineers, middle manager, and VPs. It's also nice to work on a product, where the BOM cost is not always the main focus. Apple will spend money on whatever equipment or resources are required to get the job done.
Inconvénients
Sweatshop through and through. They like to keep teams very lean, the hiring process is so gruelling that few make it through. This makes for very long days, usually 12-14 hours. Very confrontational interactions between teams, by this I mean the normally collaborative atmosphere between teams is more like in-laws fighting at Christmas. Traveling to China 6+ times a year.
