Pay was good as is the case with most large oil and gas companies. Good access to on the job and classroom based training.
Cons
Upward mobility was extremely limited and reserved for those related to upper management aka "Chevron babies". A noticeable group of employees were recruited on this basis and promoted.
Good career, excellent engineers, teamwork environment. Always different projects to work on and thought out and multiple.
Cons
Chevron is very large, can be a little difficult to change and current project seem to be either to short or to long with out being told at the beginning.
