Applied online. A few days later I was asked to come in for a local on-site interview. I was interviewed by three people, including one who was a first year in the LDP. It began with "walk me through your resume" and then I was asked behavioral questions. Then I had about ten minutes to ask them questions. A couple days later, I received an email to attend the final round of interviews at Raytheon's headquarters near Boston. They flew us out and put us in a nice hotel. The first day was a business formal networking event and dinner. Although those events were more relaxed, they were certainly part of the decision-making process. The next morning there was a breakfast, followed by five back-to-back 30 minute interviews. All candidates were well-qualified, so the process was more to see how each might fit into Raytheon's company culture, how they work in teams, etc. These interviews were either behavioral, or a normal conversation, it depended on who you spoke to. After the conclusion of the interviews, we had lunch. After lunch was the case study. We were put into groups of 3-4, and given an hour to prepare with our group. People came in and out to observe. After that, we had 15 minutes to present and answer questions. I'm told they wanted to see more how we work in a team than the conclusion we came to for the case study. After that ended, we said goodbye and went straight to the airport. I received an offer over the phone two days later.
