Do you mind taking a 3 days of tests? Required 3 days of tests at the Duke testing center. Tests were pretty hard and not relevant to the job at all. Discussed tons of science such as uranium fission, glad I have several degrees and was able to pass the tests. However, seemed a little strange that the questions were so far from project costs, not related to the work at all.

Describe how a PID loop works. What parameter do you adjust when the process variable is unable to reach setpoint. How would you go about troubleshooting a PLC problem? Asked me about safety PLCs and what I know about them. What is difference between a permissive and an interlock. I had trouble saying it, and he gave me his answer. He knew that I understood the difference but just didn't know how to put it in words. Overall, great people who are very motivated.
