Lockheed Martin interview questions

Attended a job fair in Philadelphia in 1999 and visited the Lockheed Martin booth. Presented them with a copy of my resume which had absolutely no work experience for the position I was applying for, but I was a Math major with a minor in Comp Sci. Called back for 1 on 1 interviews with 3 managers and one senior software engineer. Offered entry level position within one week. Interview process was easy and was not surprised with any questions that I considered difficult to answer.
