Pros
Friendly co-workers, inclusive culture, good work/life balance, most people get every other Friday off. I have been treated well and have never been asked to work through nights or weekends. Overall the company is a well organized and well run machine.
Cons
Little career growth potential in the SF bay area, especially with low oil prices and recently announced lay offs (many jobs being relocated to Texas or overseas anyway, eventually HQ expected to go to Texas as well). Not a progressive culture; being a 100 year old oil company it is more interested in preserving the status quo than investing in alternative/renewable energy sources that we will eventually need to convert to. HQ in San Ramon feels very sterile and quiet despite its size. Plenty of room and potential to make it a much more lively and compelling office campus. The company is extremely image conscious and pushes the espousal of safety to absurd limits, especially for an office environment that does not come with the same set of industrial dangers that a refinery or an exploration field would.
