Sent an email stating I would be contacted for the interview. I was called later and travel was set up to Tucson. Raytheon paid for the Airfare, rental car hotel and a per diem. The process was difficult due to several circumstances, but everyone was extremely helpful. They even worked on days off to ensure I made the interview. The interview itself was professional, straight forward and relatively causal. The experience increased my motivation to work for Raytheon.
