When I interviewed for this position, it involved the manufacturing plant manager and his superior, the VP of manufacturing. The interview started at 10:00, they took me to lunch, and ended at 2:00. Free lunch alert! But trust me, you will earn it because they ask questions pertaining to their immediate problems. The plant manager knows what he is doing, however, the VP has an idea of business and conformity to requirements, but not of manufacturing. How can a VP of manufacturing be so reliant on a plant manager? Looks odd, but keep a poker face. They are no-nonsense and feel a bit provoked if you expand on manufacturing. Keep it simple and talk slowly...don't talk with your mouth full at lunch.
