First technical screen - 45 minutes - talked about stuff from my resume, followed by basic questions about applied aerodynamics, flight dynamics, stuff like if you are in an airplane and you activate aileron, what happens to the altitude, speed etc. Take home design assignment - 6-7 days of time 1 hour interview - Design problem - design a system to clear water off the camera, while flying Project presentation to a panel. Final round - Highly technical flight dynamics questions eg. which parameter decides how quickly a fixed wing plane can gain altitude etc.

First round interview I did was a technical interview with an engineer on the aerodynamics team. Following round would have been a technical presentation about a project I've done to the team, but didn't make it to this stage.
