I submitted an application on-line through the Northrop Grumman careers website. 20 days later I received an email from HR asking to set-up an on-site interview. The interview was set for the following week. The interview took a total of 2 hrs. It began with a tour of the facility (~1hr) and then a panel interview with 4 people: my hiring manager, the person that gave the tour (my supervisor), and two other people from different departments. They started with "Tell us about yourself" and then took turns asking STAR questions. ie "Tell us about a situation where you had to convince others of something using logic/facts." and other topics like working in groups, managing multiple tasks, communication etc. Nothing technical or difficult. Then they asked more straight forward questions like "What is most important to you about a job?" "What is least important?" "Are you willing to work off shifts?" The interview concluded with the hiring manager saying it might take a while to hear back, and then I was escorted out to the main entrance by someone who had just recently been hired. It was a 5 minute walk so I was able to ask how his experience had been since he began. He said positive things and bid me farewell.
