Pros
It can be mildly exciting whenever a new product surfaces and you get to join co-workers in a collective ego massage at the keynote. Also at said keynote, workers sometimes get free product, and that is a bonus when it's the iPhone. There are coaches going back and forth to SF from Cupertino and back, which is a plus.
Cons
There has been a consensus for a long time, even its among top engineers, that Apple does not tend to promote people or compensate them fairly. Have you ever seen Apple on the Forbes 100 Best Places to Work?' Enough said. You will be just a number to them if you decide to join their ranks. The focus is purely on product and the bottom line, which of course is no surprise in the corporate world. But if you're a corporate hooch, I guess you won't mind that. 'Think Different!' Ahem. And here's some juicy gossip: Steve is afraid of donuts! How do I know? Because he banned them, along with balloons from Macs cafe. He also has a fear of buttons. Origin of this phobia - unknown. But here is what you should be afraid of my friends; the tendency that Apple and just about every company these days has to keep Permatemps. You may want to board the Mother Ship so badly it hurts, but take my advice and do it the regular way, through the Apple hiring process. Don't go through an 'agency.' Basically they are in the business of laundering...people. These are shady operations that are not even real companies and are in cahoots with Apple to deny you benefits or any basic rights, all while forcing you to do the same work and keep exactly the same hours as employees. For what? Surely not for your benefit.
