Welcome to your interview.
The question is on your right: Fraud Scenario Roadmap. 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.
If a person who generally spends $10,000 per month suddenly ups their spending, what road map would you use to investigate fraud and communicate next steps?
