I applied online. The process took 4 weeks. I interviewed at Northrop Grumman (Orlando, FL) in Nov 2015
Interview
They contacted me via email and asked me to come in for an interview in a day or two. It was really comfortable, lasted about an hour. They just asked about my past experience. Told me they would let me know if I need to come back for a second interview. That was over a month ago and still no response.
