Pros
Apple is the kind of place where they throw you in the deep end very quickly and expect you to produce results. There is very little hand holding --- but since *everyone* has been in the same boat, folks are usually very good about answering questions If you can survive and excel in that environment and if you believe in the product and the mission of the company (without being an obnoxious fan-boy), this is a fantastic place to work. The company expects productivity and results, but also is very good about giving you the space you need to get the work done on time. Mico-managers (and those who require micro-management) need not apply.
Cons
Due to the secretive nature of the Company, employees sometimes won't know exactly what they are working on will be informed about a lot of important difficult work they have to do at the last possible minute they would need to be informed about it. The hands-off management style can lead sometimes lead to a lack of feedback. Becasue the attiude aroudn here is "do whatever it takes to get it done" thee can be a lack of work-life balance -- you can take whatever personal time you might need, but you still have to get stuff done on time.
