Vantaggi
relatively stable in terms of incoming revenue/jobs. however, even though it's a large company don't expect to get much cross discipline experience; the company divides jobs between disciplines severely. so if you are looking to develop skills in both science and engiineering fields you won't be able to. also each office works entirely differently so one office may not produce the same quality product as another and as a client you never know what you are going to get. offices also don't generally work well together.
Svantaggi
very corporate; only interested in profit not interested in client satisfaction, employee growth, quality of product, or innovation at all. there is definitely a sexist bias in terms of promotions, opportunities, salary, and raises. women with the same title, experience, and skillset are frequently paid less and given less promotions than those around them at the staff levels.
