Pros
You gain a lot of exposure and experience. You don't have to worry about not having enough work. Lockheed pays for your masters. It is a friendly environment for the most part. You will make a lot of friends working for this company.
Cons
Management gets away with giving an entry level employee work meant for upper levels. Then, when it is time for your annual pay performance raise....lets just say, the raise they will offer you is a slap in the face with the amount of work you put in. Also, if you have a weak link in your group, expect to take on additional work. Don't be surprised if the weak link doesn't receive an discipline either. People who suck up the most and/or in LDP roles are more likely to get level increases or higher pay raises, even if they have no idea how to explain the reports they pull and put into Excel spreadsheets.
