Vantaggi
Stability and great experience. With such a large company there are vast opportunities to work in a variety of places around the world. Also communication and collaboration is very impressive with such a large company.
Svantaggi
It is a very slim and trim operation. There's a reason why it consistantly makes a great profit than similar comapnies because of disciplined management. So the perks and fringe benefits you might see at smaller companies are not here. Also because it is the biggest and most profitable, it is also the most hated and everyone likes to put its sights on the company. There are no official 9/80s but the flex schedule program is a good if not better surrogate which allows for very very flexible work hours. The flex schedule is probably a greater advantage to employees with families and children but is still very useful to single employees.
