Eight Manufacturing Engineer interview questions, and what the interviewer is thinking

1. What does a manufacturing engineer do day to day, and why does the role appeal to you?

Why they ask: To check the candidate understands the role's position between design and production.

2. What is design for manufacture and assembly, and how would you apply it when reviewing a new product design?

Why they ask: To test the core manufacturing engineering skill of influencing design early.

3. How is takt time calculated, and how would you use it to balance an assembly line?

Why they ask: To check core line design calculations.

4. What is GD&T, and why is it used instead of simple plus-and-minus tolerances?

Why they ask: To check drawing interpretation at the level a manufacturing engineer needs.

5. When you introduce a new product to the line, what documentation and process definition do you produce?

Why they ask: To check process planning practice.

6. Operators tell you the new work instruction you wrote isn't workable and they've started doing it their own way. What do you do?

Why they ask: To test humility and process discipline.

7. What is SMED, and how would you apply it to a machine with long changeover times?

Why they ask: To check changeover reduction technique knowledge.

8. Tell me about a time you introduced a new product, process or piece of equipment onto the shop floor.

Why they ask: To assess practical project delivery.

A sample answer to question 1

What does a manufacturing engineer do day to day, and why does the role appeal to you?

A manufacturing engineer makes sure products are made efficiently, safely and to quality. In a typical day, I might help the line on a process problem, then move to improving a work instruction, reviewing a design change for manufacturability, looking at cycle time data, or specifying a fixture or tool. I'd liaise with production supervisors, quality, design, maintenance and suppliers, as most improvements need all of them. I'd also be working through projects, like introducing a new product, relocating a line or justifying an automation purchase. The appeal for me is that it's very tangible: you can see the result of your work on the shop floor, in less scrap, shorter cycle times or a safer job. I enjoy the practical side as much as analysing the numbers, and I like working closely with operators.

Common mistake to avoid: Describing it as a maintenance role; focusing only on desk-based analysis
