Lockheed Martin Systems Engineer interview questions

Very formal and a group process. Light snacks and an introduction first. Interviews were then a "lightning round" format. Every interview was only allocated 30 minutes, which means only about 20 minutes of real interview time. Shortest interview I've ever had, even for candidates that crossed the country. The manager was asking the next question before I finished my answer. Very rushed and incomplete feeling. Be prepared to give quick, succinct answers. I was not told until arriving that the interview would be only 30 minutes.
