Pros
It's a big company and it looks good on your resume. Lots of cool projects to work on.
Cons
Lots of politics. Lots of hierarchy. They do a terrible job retaining top talent. They layed off a bunch of really bright employees and kept the yes folks. It's no wonder the business has to grow overseas. The engineering is okay. The science is really subpar. The creative folks are not encouraged to be creative. GE's greatest strengths are its name and its marketing, because people still view it as the great American company. It's become a me-too company. Lots of acquisitions. Organic growth is non-existent. The So-called global research centers are a technological farce at best these days. Lots of projects, but they get canned all the time. The R&D is terrible because it's at the mercy of the businesses.
