Pros
GE is a very diverse and dynamic organization. If you are the type of person who will actively manage their own career, opportunities abound. However, you must be willing to relocate to just about anywhere in the world to truly be successful. The employee experience really varies from one business to the next. Overall, the benefits and respect for employees is good. Of course, there are some businesses where this is not the case. The good thing is, every 2 years you are free to apply to any internal job your qualified for!
Cons

It is entirely possible to land in an unsuccessful business without even realizing it at first. Once there, it is hard to get out....
