Lockheed Martin Mechanical Engineer I interview questions

I met a recruiter at a MAES conference in Houston, Texas and was offered an interview on the spot upon him reviewing my resume. At that point, I was put on a waiting list and then taken to the back for an interview. The interview questions consisted mainly of the recruiter asking me about projects and coursework that were on my resume. Apart from that, he asked what particular division I would like to work for if I were offered a job and why. Since I was asked for an interview on the spot, I wasn't prepared and hadn't researched Lockheed Martin prior to the interview so I'm pretty sure that's why I did not advance in the interview process. Some advice: Always research the companies you want to work for in advance just in case a surprise interview comes your way.
