Vantaggi
It is a great place to start your career. It has several training opportunities. It is perhaps the only place in Brazil where engineering is done at a high level and in large scale.
Svantaggi
It is difficult to move among different positions. Once you reach a certain level it gets even more difficult as the salary increases and very few opportunities are given to the ones with experience (and have the highest salaries). The company has no policy for expatriation so the company misses the opportunity to create a truly globalized environment (with workers from abroad in Brazil and vice-versa). We usually say that the company is a "multi-local" company, instead of a multinational company, as it is in several countries, but the sites are all segregated.
