Pros
Old professionals with a long experience at the company are great. It's an outstanding place to learn O&G related technical skills. The HQ facilities are magnificent. In the beginning is exciting.
Kontras
With six management in about a little more than a decade and the last nationalization, corporate culture has changed so many times to the point that now it's negative or even non-existent. Don't expect work-life balance at all. Being the major company of a country, there is a very conditioning tacit belief that there's nothing "out there". No training. Promotions and benefits are based on favoritism. The company it's not suited for those unwilling to put most of their energy on facetime and internal corporate politics. Current and future situation are absolutely related to national politics.
