Pros
ECS does offer the ability to obtain a Secret & TS/SCI clearance, making it a great opportunity to get a foot in the door in the intelligence and contracting world. For imagery analysis, the day-to-day work is consistent and you're able to work independently without being micromanaged. Bonuses are offered; however, minuscule at that. The workplace can be very enjoyable when you're with a good group. Great team collaboration environment and workplace diversity.
Cons
While the day-to-day work is consistent, at times it can be tedious if you're looking for diversity in daily tasks. There is also a noticeable gap in communication from upper management and there's little opportunity for upward career mobility--including promotions. Unfortunately, nepotism is also awry in some departments, alienating good employees.
