I applied online. The process took 4 weeks. I interviewed at Air Products (Breinigsville, PA) in Oct 2016
Interview
Started with a phone interview, then an on-campus interview with HR and then a panel of possibly coworkers. Basic questions for the field practices and overall competency in the area. This should be fairly straightforward for someone with the proper background in controls.
Interview questions [1]
Question 1
How do you test systems to ensure they function correctly before installation?
