Welcome to your interview.
The question is on your right: Calculating and Revising EAC. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How do you calculate Estimate at Completion (EAC), and what factors would cause you to revise it on Northrop Grumman programs?
