Manufacturing engineers will need to work closely with production and operations managers during the course of their career. Many times, manufacturing engineers operate in support roles to these types of managers. Operational managers will assign tasks to manufacturing engineers, but are not usually their direct supervisors. It is important that you show you will take direction from and work well with the staff you are supporting. Also, it is important to show that you understand your project schedules (and often your personal work schedule) will be determined by production needs, which can be quite dynamic.
