I have been working at Phillips 66 full-time (More than a year)
Good salary, good bonus, plenty of growth opportunity, great co-workers
Company has a rotation program, but is not very effective
I applied through college or university. I interviewed at Phillips 66 (Bartlesville, OK).
It was an all day on-site interview for PhD candidates. It included a seminar where you give a 45 min presentation on your work, and answer technical questions. Afterwords there are 5-6 different interviewers that rotate between technical and behavior.
