Pros
Work / life balance is truly honored here. I have a young family so this is something that is big to me. Pay is decent, decent bonus structure, but nothing life-changing. Wide scope, there are so many places you could work at Chevron, so my experience is highly unique, just like everyone else's. If you get in with the right group it could be a sweet deal.
Cons
Downtown. This is obviously dependent on where YOU live, but for me the commute is horrible. It steals 2 hours of my life everyday, sometimes more Politics - lots of favoritism disguised as career progression. When work gets slim, all the work goes to the group favorite. Highly Bureaucratic - Processes for the sake of process. If you like taking months and months to make seemingly simple decisions because the process says so...then you'll love it. There's lots of places to go, but many many walls and roadblocks to actually getting there. The safety culture is taken to a nanny-state crippling extreme. I got snapped at for turning my head while riding down an escalator "look forward please". Gimme a break. Dare you to say something like this out loud...best have your resume polished.
