Lots of opportunity

Pros

There are lots of opportunities working for such a large company; it just takes initiative to seek and go after those opportunities.

Cons

In a company with more than 14,000 employees, it is easy to get lost in the sea of names executives deal with every day. Sometimes management focuses more on numbers instead of on who is making a difference in the company.

Pros

You get to work with some of the best scientists & engineers in the business.

Cons

Extremely long work hours when you have a project. You have to find your own projects on your own time and you receive no management support. You will be laid off instantly if you are not charging your time to a project. No recognition for a job well done.
