Pros
Roche is a company that is really willing to invest in people who are willing to make an international career. Fact is that in order to make a major career at Roche, you should be prepared to work abroad for several years. Roche Diagnostics Brasil Ltda in Brasil is a separate legal entity from Roche Pharma Brasil, with its own management, IT systems and company policies. As it is much smaller in size to its Pharma sister, yet has a similar management overhead, there are probably better career opportunities here. The company has a relatively young management team and has again and is not afraid to promote young people if they deliver results and are politically astute.
Cons
If you want to stay in Brazil, and are not willing to work abroad, you may not achieve a General Management or Finance Manager position, which are traditionally more intended for expatriate managers or Brazilians who have worked abroad and/or have established good connections to headquarters. But that is true for many other multinational companies as well. There have been several major changes in management, organization and even culture in the last years, which would leave every company in a state of transition and anxiety about what comes next. The company gives interesting challenges to talented employees but often with little formal classroom training. Be prepared to be thrown into cold water and learn to swim for yourself.
