Pros
Good solid company to work for with a lot of opportunity to grow. Pleasant work environment and I get to work with many bright and motivated people. The management style is also very good in their way of engaging employees and always having an open door policy where you can walk in anytime to let them know what's going - and when the news is bad they don't shoot the messenger. Genuine work-life balance. They respect employees right to a personal life and there's seldom a need to have to work on weekends or late at night. The nine day fortnight system is a fantastic benefit. Pay & benefits are good, probably are some higher paying employers around but when you look at the whole deal (esp working hours etc) I think you'd battle to beat Chevron
Cons
All of what I wrote for the pros are about my time working for Upstream. Previously I worked in Downstream at a refinery and it's like working for a different company. Effectively zero career progression and some unpleasant office politics. Probably the worst was the policy of never promoting top level managers from within - always had to be expats or someone recruited from outside of Chevron. Understandably this upset a lot of people who realised there was no chance of ever moving up. Compensation sub par (especially for some technical skills that local management was not aware that they had or even need!) compared to competitors - although in fairness the work life balance was good.
