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.

Straight forward - 30 minutes phone screen with behavioral and technical questions on C++. Followed by 5 hour in-person or virtual interview which included both technical and behavioral questions. Each hour was a different interview with different people.
