Pros
Chevron has a really collaborative work environment and everyone is willing to help you if you ask for help. Chevron has also let me move from job to job across organizations so I could get a variety of experiences and I have been given a variety of challenging jobs. Generally top management is also very good. The flexible work schedules are also excellent. I especially like getting every second Friday off.
Kontras
Like many companies, the quality of first line supervisors and middle management is hit and miss. If you work for a great supervisor you have a great time. If not, then not so good. None of the supervisors are bad but some don't really do a good job managing newer employees. Also, the whole company is extremenly busy and its easy to lose your work-life balance if you aren't careful.
