I applied online. The process took 2 weeks. I interviewed at CITGO (Houston, TX)
Interview
95% behavioral/circumstantial questions. "Describe a time..." It was a committee interview and they took turns asking questions. There were some technical questions pertaining to the required experience needed. It took about an hour. Most of the questions involved conflict resolution.
Interview questions [1]
Question 1
