I worked at Chevron full-time (More than 5 years)
Chevron has great benefits, recognizes and rewards their employees and has a very strong company culture that's consistent through at all it's companies across the corporations.
Because it's so large it tends to be conservative so, some things can move more slowly than in a smaller company and are not as fit-for-purpose.
I applied online. The process took 2+ months. I interviewed at Chevron.
I was emailed about a week after I submitted a resume for a phone interview. There were 2 people on the phone interview and they asked very generic questions - e.g. describe yourself, what type of contracting work have you performed. After about 2-3 weeks I was called in for an in person interview where they asked basically the same questions again, but this time I was interviewed by a 4 member panel. People were very nice and one of them gave me a card and said to call anytime with questions. Also had to pass a drug test and background check.
There was no negotiation.
