I applied on their website and got an email for an initial phone interview later that week. The man interviewing me asked some pretty technical questions. The team I was interviewing for wrote the autopilot system for their UAV's. The programmers need to know C programming as well as how aircraft fly to be able to understand how the coding would affect the aircraft mid-flight.
Interview questions [1]
Question 1
Asked how a plane turns, how memory is allocated in C, Stack, Heap, Pointers. Not asked about actual code in this interview.
