Pros
Chevron provides a great opportunity for new hires to get a high level of training (on the job and in the classroom) and gain experience in a wide variety of assignments early in a career. Chevron has a very experienced work force that serves as valuable mentors to accelerate your learning. This "aging" work force also means that younger employees will be able to advance their career more quickly as the baby boomers retire. In my 8 years with Chevron, I found that all managers I worked for stood by Chevron's commitment to a work/family balance.
Cons
Since Chevron is an international company, they put a very strong emphasis on being "globally mobile". You have to be willing to follow their "suggestions" about when and where to move in order to stay on "The List" and continue to be quickly promoted. With the energy industry so focused in Houston and a spouse that works for another energy company, we were not mobile. I made the hard decision to leave Chevron because I knew that my career would stall when I refused to move. I can now stay in Houston doing the work I truly enjoy with another company while getting higher pay and no pressure to relocate. Also, although Chevron has improved in recognizing the importance of technical expertise, they still put much more value and emphasis on people who want to pursue a career in management versus a technical career.
