My interview process was 100% virtual.
The company hosted a virtual information session at my university about the LDP program and to apply online.
About a week after I submit my application, I had a phone interview with a current manager that had gone through the LDP program themselves. I then completed a HireVue the same day with the same questions the manager asked me.
About two weeks later I get invited to the final round which is called Super Day. In the few days leading up to Super Day, I am told to create two PowerPoint presentations to be presented on Super Day. One is a case study that requires me to form solutions to the situation described, and the other requires me to identify a current problem facing the company and to create a solution for it.
The Super Day was virtual, though I was told in the past candidates were flown out to Raytheon HQ at this stage.
The actual day consisted of presenting your PowerPoint slides, a panel interview, and a group collaboration where you have 15 minutes to brainstorm and then present ideas. In between all this you are networking with Raytheon employees in breakout rooms.
Offers were extended shortly after Super Day.
