Pros
BAE Systems is using some amazing technologies and doing R&D to create new ones. The level of expertise and potential is something to witness. Many employees who are not in management are really friendly and dedicated.
Cons
During my time at BAE Systems, I found that most people were highly stressed out and not enjoying their work. I was having nightmare dreams at night regarding the office, in fact. The corporate echelons have a culture of silver-platter/white glove service. Honestly, I don't think this corporation values its workforce at the highest levels. The only exception to this is Erwin Bieber, President of Land and Armaments. I cannot say enough good things about this man and how he treats those around him. I wish he weren't the exception, but sadly for the rest of them it's mostly about status and the bottom line.
