My advice is to avoid this place like the plague unless your goal is to coast until retirement while working on extremely outdated tech. As an engineer, working at Lockheed for more than about 5 years is career suicide if you have aspirations to work at a real tech company. You would have been working on tech that was cutting edge 20 years ago. Prospective future employers who do actually contact you will certainly ask "Why did you work at Lockheed Martin?" in a way that sounds like "Why did you work at a garbage dump?" The implication is that you're supposed to defend why you worked at such a bad company filled with mostly lazy people who want to coast until retirement. You'll have to explain that you were one of the few people who weren't like the majority there. Additionally, Lockheed only values how many years you have been working, and merit is completely ignored by management. Anyone smart quickly leaves and every location I visited was filled with only old people about to retire along with a small number of clueless new college hires who haven't caught on to how bad their job is yet. It was my first job but luckily I escaped after realizing what this place was about without too much damage to my career.
