I applied through a recruiter. The process took 4 days. I interviewed at Lockheed Martin in Apr 2015
Interview
The interview was fairly straight forward, somewhat informal, but that was actually refreshing, as the interviewers wanted me to relax a little, to see what kind of person I really was. The interview was different for me, as it was over the phone, instead of in-person, but this wasn't an issue, as I was prepared ahead of time, and had all my documents printed out and any questions that I wanted to ask, also printed out. This helped immensely. Being prepared is vital to any interview.
Behavioral interview. Was flown out, got to meet several of the managers who were very kind people. All round behavior interview with interests in prior projects or work experience. There were some technical questions but nothing out of this world. Also got a background tour of their facilities. The interviews were individual but in a group format. They would have a big group of 10-15 come to the event and then the managers split the interviewees based of the skills set. I had 4 interviews with 7 different managers from different departments.
The process took 3 weeks. I interviewed at Lockheed Martin (Syracuse, NY) in Apr 2015
Interview
I applied online and was flown out. I did not have a phone interview beforehand. It was not an "interview day" like the others spoke of with many people. I was taken up stairs and interviewed without any other candidates around. There was a panel of 3 people. One person I believe the division manager, then there was an analyst, and an administrative worker. They had a three page document of questions, (it looked like they skipped some). The question total was around 12-15. Everyone was extremely nice, and easy to talk to. the questions were all your average behavioral questions. The only problem you might run into is thinking of enough experiences which a different from the last for each answer.
