First call was with an HR representative. It was very short about 15-20 minutes. I feel it was more of a feel to see if my personality and goals fit with the position and group Second call was with a fellow at Raytheon asking technical questions. Again, it was short and lasted only 25-30 minutes. Third call consisted of the hiring manager, division manager, and the fellow from the second interview. This was a lengthy interview (1hour and 15 minutes) delving deep into the methodology of my work ethic and procedure. many questions were asked about the solution process to projects I have worked on. There was also conversation about the location and very briefly on the position responsibilities. Fourth interview consisted of a location visit which involved a tour and meeting other coworkers in the team. This visit lasted all day.

Very straightforward process of 3 rounds: 1 virtual interview, a call with the hiring manager and 1 in-person interview with the department management team. Received offer within 4 days of in-person interview.
