Lockheed Martin Senior Software Engineer interview questions

I received a phone call to arrange an face-to-face interview a couple of weeks after submitting my CV through the LM site. There were no tests or phone interviews beforehand. The interview was held by one team leader and one program/product manager and was extremely high level, mainly made up of run-of-the-mill HR style questions. It lasted 30-45 minutes. Only one real technical/programming question was asked, despite that being the main focus of the role I was interviewing for. The sample code I was asked to improve was very basic (not a real world example, only a few lines) and had no context associated with it. It was obvious there was a "right answer" the interviewers were looking for but although I suggested several improvements, with little surrounding information I could not find that right answer and it was clear that that was the end of my chances of securing the role. The interviewers very much stuck to the printed questions on the sheets in front of them rather than having a real interest in my experience or abilities. I wasn't asked to run through my CV or discuss any projects I had worked on even though they were very relevant to the opening. I received a standard rejection email a week later.
