Machine Operator Interview Questions

Machine operators set up, control and maintain machines. They work typically in manufacturing and production but may also be found in other functions such as packaging and filling.

Generally,  a high school diploma is enough to enter this profession. Some related experience is often required but not always, since a lot of on-the-job training is involved. Strong technical aptitude should be reflected in the candidate’s resume.

Questions can be divided into four categories: technical knowledge (machines, measuring and procedures), quality control, safety and collaboration. All of them address a set of skills that are vital for machine operators. If your company uses a specific type of machine, you can ask them how familiar they are with it. The ideal candidate will demonstrate a commitment to doing things the right way.
