Pros
Perks, salary and benefits are great. The culture is very positive. I get to work with some extremely smart people and the social atmosphere is very friendly. They are also really good about letting you move to other positions within the company once you are an employee, so there are infinite ways to grow your career, which is great, because I don't want to go anywhere. Without negotiating, they gave me a generous stock award as a signing bonus (pretty sure that's standard) and they also have an insane employee stock purchasing plan that allows you to buy Adobe stock at a 15% discount from the lowest price over a 2 year period... It's free money.
Cons
I haven't found any yet... I mean, if you hate working for a big company, it might not be your thing. That said, there are a lot of small teams within Adobe that work like smaller companies, but with the benefit of the cushy benefits and stability of a big company like Adobe.
