Vantaggi
It's difficult to rate the whole company because it is so big and has a very wide range of careers and jobs to offer.
Svantaggi
In my group it became quickly apparent that technical skill and the ability to do the job well was not an important factor for the management when deciding to hire or keep personnel. I was astounded by the selection of very unqualified individuals to fulfill fairly technical rolls as well as the "laying off" of very skilled technical engineers. At this point they are basing almost all decisions on "cost savings" it seems. Including myself my team had lost 3 people in the last 2 years, and none are being back filled. On top of that the workload basically doubled over the last year due to a new contract being signed.
