Hiring process is slow but comprehensive and you stay well informed. Waited for interview notification for one month after applying online. Interview was pleasant. Everyone was pleasant. Spoke to two different managers and one engineer and one HR person. It felt relatively laid back and informal for an interview. There were no difficult/annoying/stupid questions. All questions were about technical ability and concerns about Raytheon that I may have. No personality/what if questions. Took half a day ~3 to 4 hours.

They will reimburse you if you drive more than 60 miles to the interview (ask) and they will fly you in.

Was asked the difference between two Java concepts. Was not entirely sure but had an idea and it was OK.
