Behavioral Questions

Describe a project where you solved a complex mechanical failure.

Show root cause analysis methodology, testing, and the solution you implemented.

Tell me about a time you had to balance performance, cost, and manufacturability.

Show trade-off analysis and cross-functional collaboration.

Technical Questions

Walk me through your design process for a new mechanical component or system.

Cover requirements, conceptual design, analysis (FEA/CFD), prototyping, and validation.

How do you select materials for a given application?

Discuss mechanical properties, environmental factors, cost, manufacturability, and standards.

How do you approach tolerance analysis and GD&T in your designs?

Cover tolerance stack-up, critical dimensions, manufacturing capabilities, and inspection methods.

What CAD and simulation tools do you use and how do you validate your models?

Cover specific tools, mesh refinement, boundary conditions, and correlation with physical testing.

Situational Questions

A product is failing in the field but passes all lab tests. How do you investigate?

Discuss environmental factors, loading conditions, field data collection, and test-versus-use gap analysis.

Your prototype does not meet performance targets two weeks before a deadline. What do you do?

Discuss root cause analysis, rapid iteration, risk assessment, and communicating with stakeholders.
