Lockheed Martin interview questions

I emailed with a recruiter to schedule a phone interview with the Lockheed Martin hiring manager and his panel of associates. I was given some initial information about the job and department, then I was asked a series of questions by several different people consecutively. There were a lot of detailed technical questions that I was barely able to answer (I should have reviewed concepts first!), but after that I enjoyed the discussion a lot more. There was discussion of my accomplishments, as well as soft skills. At the end of the interview, I was given plenty of opportunity to ask as many questions as I liked. The whole phone interview lasted about an hour-and-a-half. Surprisingly, I was given an offer without an in-person interview. Overall, despite some tough technical questions at the beginning, I quite enjoyed the interview and everyone on the panel was very encouraging and generous.

You will go to a conference room and there will be probably about 20 other interviewees. Includes Interns, full times. Then managers gather into the room and introduce themselves, telling you what role of people they are seeking. They then begin to pick people out to interview with.
