Applied during my last semester of college and took about a few weeks to get the offer. Spent the day being interviewed at HQ by four of six different people (I don't really remember). Interview consisted of behavior and technical questions. All of them I thought were straightforward and basic. The highlight of the interview is seeing their labs (what cool gadgets), getting a free lunch (food means a lot to starving college kids) and ridding the escalator. Seriously they have one. Some questions were Where do you see yourself in 5 years? What is a abstract class? What are your hobbies? Do you have an interest in avionics?

They provide you with an on-site tour of the facility and explain each department. Part-way through some of the tours, you stop by a meeting room and meet with an interviewer who discusses some technical (mostly behavioral questions)
