I applied through college or university. The process took 1 day. I interviewed at Sunoco (Philadelphia, PA) in Feb 2015
Interview
On Campus Interview. They asked the standard tell me about yourself questions, as well as other resume related questions before finishing up with a brief case study/brain teaser. The introduction of the program was a big vague and hard to gauge the actual responsibilities of the position but both interviewers were friendly and enthusiastic.
Interview questions [1]
Question 1
Explain a difficult situation you encountered while working at X and how you resolved that situation.
