Pros
Great work/life balance! 9/80 work schedule allows the employees to pursue various personal interests over 3-day weekends every other week. Also, pursuing advanced education is strongly supported by providing 75% tuition reimbursement for taking classes while working full-time. Due to its extensive global presence, there are numerous opportunities to work overseas if one desires. You can "switch" careers within the company without quitting by internally posting for open positions.
Cons
So-so pay. Because so many people at Chevron are "lifers" (e.g. average length of employment within its IT company is over 20 years!), it takes a lot of years to really advance upward in your career ladder. Although part-time school education is strongly supported, leaving the company for a full-time program (i.e. full-time MBA) would seem out of place here since not many people do it.
