Pros
The pay is good. However, I was hired by a different company that was acquired by HII.
Cons
There is a constant shuffle of upper and middle management. You will be working for one person for a few months before you are handed off to another person. Many times it makes no sense to you or your management why you are working together. Middle management is so afraid of being fired that stupid decision making in upper management goes unchallenged. Then those poor decisions end up falling on lower level employees to resolve. Communication is extremely poor. Decision making is made without input from the people who will end up doing the work. This is the worst environment for software development I have ever encountered in 20 years as a software engineer.
