Short, mostly behavioral, no hard technical questions other than describing my past experience to more details than is on my resume. Felt like a formality and that an offer was already on the way.

Interview was mostly behavioral designed to see how well you work in teams and if you have the capacity to lead. If you've been through one behavioral interview you've been through them all just about. With that being said make sure you anticipate these questions and have bullets on your resume that already answers these questions. The less the recruiters have to ask the better. As a defense contractor Raytheon will require you to be able to obtain a security clearance. If you are not a US citizen your best bet is to look at private sector jobs because it is very hard to progress in a company such as Raytheon and be foreign.
