I applied online. The process took 2 weeks. I interviewed at Chevron (Bakersfield, CA) in Jun 2014
Interview
Friend discussion at first. Ask a lot of STAR type questions. Be ready for behavior (what if) situations. The Engineer asking me was understanding but the Manager was more challenging.
I applied through college or university. I interviewed at Chevron
Interview
Initial screening interviews were conducted on my university campus with a couple of recruiters. Then, I was asked to prepare a presentation to deliver onsite. I was flown out to the Houston HQ for a day where I gave the presentation to a small group, got a tour, had lunch, and was taken back to the airport.
