I applied online. The process took 2 months. I interviewed at Valero (Three Rivers, TX) in Dec 2017
Interview
I interviewed with the Lab Manager, Lab Supervisor, and an HR Rep. First, they asked general questions about me and about my background. Then they asked a series of behavioral and situational questions. After they were finished with questions, they opened to floor for me to ask any questions about the position that I was applying for.
