Clarifying Questions

• Looking at the product context, I'm thinking about the scale of the problem. Could you share what percentage of large international transfers are currently flagged as potentially fraudulent, and what percentage of those flags turn out to be false positives?

Why it matters: This helps us understand the current system's effectiveness and areas for improvement. Expected answer: 10% of transfers flagged, with 30% false positives. Impact on approach: High false positive rate would prioritize reducing false flags without compromising security.

• Considering user behavior, I'm curious about the typical profile of customers making large international transfers. Are these primarily business customers, high-net-worth individuals, or a mix? What's the average transaction size we're focusing on?

Why it matters: Different user profiles may require tailored fraud detection approaches. Expected answer: Mix of business and individual customers, with average large transfers around $50,000. Impact on approach: Would influence the types of data points and risk factors we consider in our solution.

• Thinking about external factors, how has the regulatory landscape for international money transfers evolved recently? Are there new compliance requirements we need to consider in our fraud detection enhancement?

Why it matters: Ensures our solution meets current and upcoming regulatory standards. Expected answer: Increased scrutiny on cross-border transactions, with new KYC requirements. Impact on approach: Would incorporate regulatory compliance as a key factor in our solution design.
