Technical depth
Check command of SAVE International job plan phases, FAST diagramming, function cost/worth ratios, should-cost modelling and DFMA reviews; ask which estimating standards or takeoff tools they used.
Evidence to listen for
- Explains the physics or mechanism behind their work, not just the tooling
- Names the standards, tolerances, and constraints they designed against
- Can defend a design decision under follow-up questions
- Distinguishes what they personally engineered from what the team delivered
Five-point scoring guide
Cannot explain the fundamentals of their own stated specialism.
Knows the vocabulary but not the underlying mechanism; struggles under follow-ups.
Solid working knowledge for the role; depth thins out on edge cases.
Strong command of the domain; explains trade-offs and defends decisions well.
Walks through a FAST diagram they built, defends function worth assumptions, and cites cost models tied to real BOM or trade quotes.
