Avantages
Compensation is average. You can definitely get the same in other places. If you are good at playing politics, then it is a great company for you. You do not need to know anything and you'll be a manager before you know it.
Inconvénients
Work is not merit-based, Promotions and Perks are all based on politics. Even if one politically significant person dislikes you, you are limited. And the dislike does not have to be substantiated. Set low expectations for your employment. At least you'll earn average pay while working as a servant. That's typical for most of the people who work here. The work environment is based on the oil price: a high oil price means a normal work environment, low price means you can be fired tomorrow. So be on alert.
