Pros
It's a company that has way more different experiences for its employees depending on the country they are working, the contractual status and the segmente they are going to work. So make sure to review all these possibilities before making a decisition. The work experience with severaly change between one and another. They motivate you to learn new thing, take you out of your confrot zone, so you will be always chalenged. My experience is based on SLB Completions Venezuela
Cons
In some third world countries like Venezuela, where unemployment is very high, the company pays incredibly bad. It looks like since they now there are tons of people wishing to work, they don't care about the benefits. My experience is based on SLB Completioins Venezuela
