Hiring manager initially reached out to me and encouraged me to apply online. Weeks later the HR department called to schedule a in-person interview and arranged the travel details. I interviewed with 3 people and each of them were laid back and just wanting to hear about previous work experiences.

One phone interview with 4 Raytheon employees. One in person interview on site with the same 4 employees. Round robin interview covered education, experience, personality and problem solving. One technical presentation to a board. I interviewed with five other candidates. We all were together and got to watch all the presentations. Senior management watched the presentation as well.
