Aerospace and defense hardware engineering internships
Avionics, propulsion instrumentation, ground support equipment and flight test at launch, satellite and defense primes. Test and validation dominate the work, so the interviews weight bring-up, hardware-in-the-loop fixtures and failure analysis far more heavily than design-from-scratch questions.
