Pros
You get the chance to work with some of the smartest people across industry. The management is top notch, and the grooming for the top performers keeps the pipeline full. It's not uncommon to see GE alumni in top executive jobs across the country. In my opinion, this is only because GE has an over supply of leaders, and unfortunately, there isn't enough room for all the talent that is brought up.
Cons
Being a top performer generally entails more than 40 hour weeks. GE does like to run lean and efficiently, meaning the peak times will require you and your team to give a little more than your salary covers. Also, the new focus on specialization and expertise has narrowed the career paths somewhat. Cross-functional opportunities are much harder to find.
