Pros: Working with great people in a very important field for the world right now. Exciting assignments and have a lot of options for growth.

Cons: It's huge. There are tons of people, and a lot of learning how to do your job is learning who to know. People also move around so often that it can be difficult to keep up.

Pros: Lots of training opportunities. The leadership programs are superb at getting top talent recognized and promoted. You can get involved in high-profile projects fairly quickly if you're talented and persistent enough.

Cons: Pay is "competitive," which means they pay only enough to keep you but not as much as competitors. It's always a little weird when people hired after you, with no experience, are paid more than you with two years' experience.

Pros: Very agile management with good business strategies. The business constantly innovates and comes up with new technologies to keep itself relevant in the market.

Cons: You end up working longer hours than usual.
