25+ Process Engineer Interview Questions

Process engineers use their knowledge of chemistry, physics, and engineering principles to design, develop, and optimize processes that transform raw materials into products we use every day—think gasoline, paper, pharmaceuticals, and the chips that make our electronic devices work, to name a few.

They also create safer, more cost-effective operations that adhere to economic, regulatory, and environmental standards. By analyzing and understanding these processes, they can anticipate challenges and innovate to keep businesses thriving.

Are you hiring a process engineer soon? Here are 34 interview questions to find the ideal candidate with the technical, creative, and strategic skills to drive your company forward.

What Skills Does a Process Engineer Need?
