Lockheed Martin interview questions

They asked me to come in for an interview. I met with three people, one from management, one developper and one team lead. They told me about the comapny, asked what I knew. Then we went into the skills testing from UML to code with some tricky questions. Then I was explained the lifestyle and how things would be.

Applied to the company through their website, submitting to about 4 jobs. Called by the company for the interview process, and mailed travel information of how to get to and from the interview site. Setup travel through the company travel agency, flew down and back, and stayed a night. Also rented a car while there on their tab. Interviewed with four people individually. Also had a group lunch with HR lead and other interviewees where I believe we were getting judged on our interaction and appearance. Each interview lasted about 30 mins asking specific details to each job. Eventually was offered a position for a job that was not included in the interview process.
