Pros
Good pay for what you do. The oil industry is very interesting. Get to work with contacts all over the world.
Cons
No bonuses, long hours, working on holidays, they do not let you respect medical leaves. Individual ranking system is based on who likes you not on the quality of your work. I´ve been harassed by the manager for the past 3 years since he didn´t like me an now he fired me with no notification after my medical leave for a hand injury they produced. The work environment is not fair, unless you smile and nod at everything they say you won´t get promoted and you won´t be treated in a professional way, they have many times tried intimidating me to get me to quit. If you have a medical problem that is generated in there, be certain they will fire you so they don´t have to ruin their precious metrics, they will die and do whatever they have to so you dont ruin their dumb metrics.
