I applied through college or university. The process took 4 weeks. I interviewed at Northrop Grumman (West Lafayette, IN) in Oct 2017
Interview
One in person behavioral interview. They ask some technical questions, but it's mostly to see if you actually know what youre talking about. They ask you about your projects and past experience. Based on what you say, they'll ask tougher questions about the topic you claimed to know.
