Welcome to your interview.
The question is on your right: Preventing Customer Churn. 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 proactively identify accounts that are at risk of churning due to low technical adoption at Nearmap?
