"People who understand production, but also have the skills to oversee and optimize the process are the perfect fit to be a production manager. In an interview context, expect to be asked questions about meeting deadlines, your experience in manufacturing, and how you could improve the company through your excellence. Be prepared to role-play a situation where some point along the production line goes awry and how you would find a solution to keep operations running smoothly. Employers are looking for candidates who are willing to go to great lengths to get the job done, so be sure to emphasize any extra time or holidays you would be willing to dedicate."
