I applied through an employee referral. The process took 2 months. I interviewed at bp (Los Angeles, CA)
Interview
I submitted my application online. A few weeks later, I received a phone call to setup an interview. The interview took 6 hours and consisted of a behavioral interview, technical interview, lunch, and a refinery tour. They had one more week of interviews after mine, and I received an offer the very next Monday after they had finished.
Interview questions [1]
Question 1
Tell me about a time you had to work with a diverse group of people
I applied through a recruiter. The process took 1 day. I interviewed at bp (Toledo, OH) in Nov 2009
Interview
Got a call about having an on-site interview, I worked in the industry so they didn't ask for a phone interview. They payed for my gas and lodgings. Got to the site early in the morning, had a small tour of the office, then got right down to the interviews. Interviewed with the two guys who would be my bosses, lots of situation questions. Then I had a skills review with two of the engineers. Lots of how does a tower run, what would you do if your plant wasn't operating well question. Overall, nice people.
