This is the kind of question where you think you're ready and then halfway through the second project you realize you've been vague about what you actually decided versus what the team decided.
Select 2-3 projects that showcase your ownership of key decisions, quantifiable impact on fraud/risk metrics, and a significant trade-off you navigated. For each, use a concise STAR format (Situation, Task, Action, Result) but emphasize the decision-making process and trade-offs. Tailor the examples to PayPal's context by highlighting scale, real-time constraints, and cross-functional collaboration.
Pro tip: Quantify the business impact in terms of dollars saved or fraud loss reduced, and explicitly state the trade-off you chose (e.g., higher false positives for lower fraud) and why it was the right call for the business.
Choose 2-3 projects where you owned key decisions and moved metrics like fraud rate, false positive rate, or detection latency. Ensure they demonstrate different aspects of risk/fraud analytics.
For each project, describe the situation and your task in 1-2 sentences, focusing on the business problem and your specific ownership.
Explain the critical decisions you made, the alternatives considered, and the trade-offs (e.g., precision vs. recall, speed vs. accuracy, cost vs. coverage).
State the measurable results: metrics improved, dollars saved, fraud prevented, or efficiency gained. Use numbers to make impact concrete.
Briefly reflect on lessons learned and how the experience prepares you for PayPal's challenges. Connect to the role's requirements.

Caught me a little flat-footed because I'd been mentally prepping to defend my modeling chops, not explain why I'd be fine without them.
Acknowledge the shift directly and frame it as a deliberate move toward higher-impact, decision-focused work. Connect your data science skills to analytics and strategy by emphasizing how you use data to drive business outcomes, not just build models. Show enthusiasm for the role's focus and provide evidence from past experiences where you influenced strategy through analytics.
Pro tip: Emphasize that you're not abandoning data science but evolving it—many impactful data scientists spend more time on problem framing and communication than modeling. Mention that you've already been gravitating toward strategy work, which is why this role excites you.
Directly address the role's focus on analytics and strategy, and reframe it as a natural progression in your career rather than a departure from data science.
Describe specific skills and experiences that make you effective in analytics and strategy, such as translating data into business insights, influencing stakeholders, or designing experiments.
Explain how this shift aligns with what you want to be doing long-term, such as having broader impact, working closer to decision-making, or solving ambiguous business problems.
Share a brief anecdote where you used data science to inform strategy, demonstrating your ability to operate in this capacity.
Conclude by expressing genuine excitement for the role and how your background uniquely positions you to succeed in it.
