Lockheed Martin interview questions

After applying online, I got a call from one of the Software Engineering Managers. He asked me a couple of questions (education, project and work experience), and then said he would like to fly me up to San Jose for an onsite interview. I told him what day I was available, and he set up 4 back-to-back interviews for that date. Each of the interviews were 30 minutes long (everyone went over - there is so much to talk about and ask!). The people there were very accommodating - asked if I needed water or anything else. Very nice people.
