"When interviewing to be a production engineer, you will likely be asked many technical questions about your understanding of manufacturing processes. Interviewers will want to determine whether you will be able to find ways to improve their production processes, whether that be through increasing safety, reducing waste, or increasing output. They will also be concerned about your ability to simplify the explanation of complicated processes to workers and managers who do not have the same education in engineering as you do. Production engineers are required to have at least a bachelor's degree in engineering."
They asked about my background and different situations that I have encountered in the work place and how I handled them. The testing portion was pretty much a general knowledge test, IQ test, personality test, and a creativity test.
