Overall Shclumberger was a great place to start, especially for new engineers just coming out of college. They're willing to teach you from scratch. With that being said, they will expect a lot of you. Long hours, days, weeks and even months away from home are the norm as this is the oil & gas industry norm.
I give them kudos for promoting from within in the company and rising through the ranks. The only reason I left was that I simply felt that the job and industry just wasn't what I wanted for a career.
High paying salary, travel, experience
Long hours, remote locations, away from family and home
