Technical depth
Probe depth in eVTOL-specific engineering: distributed electric propulsion sizing, rotor acoustics, battery pack thermal limits, and how they applied FAA SC-VTOL or EASA SC-VTOL means of compliance.
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 disk loading, hover power margins and DO-178C or ARP4754A workflow with numbers from aircraft they personally sized or analysed.
