I was contacted by phone by a recruiter. He asked about my college projects, why I wanted to work at Raytheon, and some general behavioral questions. I asked him some questions and the interview lasted maybe 20 minutes.
About a week later someone from HR I think called me. She said that they were interested and again asked me why I wanted to work at Raytheon, if I had any competing offers, and asked if I was interested in interviewing. I said yes.
A day later they sent an email with information. They flew me out to Tucson AZ.
First day, we had a lunch, then toured the plant. We then had a networking event that night.
The next day we had interviews. I interviewed for two positions. Some people interviewed for up to four positions.
Later that day they sent an email saying that they were going to make me an official offer for employment in the next few weeks.
