I applied through university. The process took 1 week. I interviewed at Valero (Provo, UT) in Oct 2015
Interview
There were two interviewers, one would scribe and one would ask the questions. It is all personality based and it was really easy going. They gave a lot of feedback, so you didn't feel like you were talking to yourself.
Interview questions [1]
Question 1
What is a time you made the workplace safer? (They are BIG on safety)
