Had an initial interview on campus, lasted about a half hour and spoke about very limited technical tasks. Was invited for a 2nd interview at Raytheon, lasted about 4 hours with 4 different interviewers. Mainly non-technical questions and focused on making sure I was a good fit personality wise within the company (Raytheon lets your resume speak for itself with regards to your academic/technical skills...expect a minimum GPA of 3.2). Made sure I had no moral obligations working for a defense contractor and was a team player. The facility in Woburn was very modern and clean and all people I interviewed with were quite nice and down to earth.
