Pros
Leidos-Life. Great work / life balance in my experience. Good middle managers in my experience. Actually does a good job at talent retention - they do care about keeping good employees (ex. if a Contract goes south, they work with you and give plenty of time to find something else within the company for you). Overall Positive.
Cons
Typical corporate politics with raises / promotions. Lack of transparency in some cases. High expectations, then delivered, with lack of reward. Numbers game instead of understanding actual problems. One experience with a Mission Directory of Software where ... they really have never written any Software. Like not even "Hello World". Leadership needs to have some knowledge of what they are leading. Overall Positive Experience though.
