I applied online. The process took 6 weeks. I interviewed at Dow (Freeport, TX) in Feb 2011
Interview
There was a phone interview plus an on-site interview with a 5 member panel. You also have to sit through an intelligence test which determines if you have any mechanical inclination and common sense.
Interview questions [1]
Question 1
They asked the standard questions such as, accomplishments and how do you handle conflict resolution. Then there were several inspection related questions based upon varying real world scenarios.
