First interview was very conversational. Very relaxed and it just felt like I was having a chat with another person passionate about aerospace. The interviewer gave me an overview of the position and the company then the rest was him poking around at my resume and what I was looking to get out of the job. Second interview felt more like a real interview (felt like more rehearsed questions and less just like a casual conversation, but that's also what I would expect). Still relatively relaxed and a good experience.

Recruiter calls you to set things up asking you a few preliminary interview questions. Then someone from the engineering department you are interviewing for calls you a few days later to interview you over the phone.
