Technical depth
Probe depth in microgravity process physics: Marangoni convection, containerless solidification, vacuum outgassing, and how they altered extrusion or crystal growth parameters versus terrestrial baselines.
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.
Explains specific process shifts caused by absent buoyancy and settling, citing measured parameter changes on real furnace, printer, or bioreactor hardware.
