Initial phone screening with HR followed by a telephone interview with technical lead involving several competency based questions and a few technical questions. Final stage was an assessment centre which consisted of listening to a presentation about Raytheon, two team-based activities, giving a presentation on a given topic with 30 minutes to prepare, and a final face-to-face interview with members of the software team. There was also a presentation given by someone who recently joined the graduate program, about his experience so far. Although the assessment day was quite long, it was overall a rather enjoyable experience and the tasks given were straight to the point so did not feel too arduous to complete. Seemed like a good way to assess everyone's ability and approaches to both problem-solving and business scenarios.
