Frame your answer around a structured operating model that you've used to align data science work with product and engineering. Emphasize early involvement, clear ownership, and iterative communication to manage requirements and timelines. Use a specific example to show how you've applied this model successfully.
Pro tip: Show that you understand the product and engineering constraints by speaking their language—reference how you prioritize based on impact and feasibility, and how you handle trade-offs. This demonstrates that you're not just a model builder but a strategic partner.
Collaborate with PM to understand the business problem and define success metrics. Work with engineers to assess data availability and technical feasibility.
Clarify who owns what: PM owns product vision and priorities, engineers own implementation and infrastructure, data scientists own modeling and analysis. Document this in a RACI or similar framework.
Break the project into milestones with clear deliverables. Use agile ceremonies (e.g., sprint planning, stand-ups) to track progress and adjust timelines collaboratively.
Maintain open communication through regular check-ins. Share early prototypes and findings to gather feedback and iterate quickly, ensuring alignment with product goals.
Coordinate with engineers for deployment and with PM to monitor post-launch metrics. Conduct a retrospective to capture learnings and improve future collaboration.

Frame your answer around a decision-making framework that balances impact, urgency, and ownership. Emphasize that you default to driving things yourself but push back when requests conflict with strategic priorities or lack clear value. Use a specific example to show how you've applied this in practice.
Pro tip: At Reddit, data scientists are expected to be proactive partners, not just order-takers. Show that you push back with data and a proposed alternative, not just a 'no'—this demonstrates both rigor and collaboration.
Evaluate whether the request directly supports Reddit's key objectives (e.g., user growth, engagement, monetization). If it's misaligned, that's a signal to push back or reframe.
Estimate the potential impact (e.g., on metrics, user experience) and the effort required. High impact/low effort requests are worth driving yourself; low impact/high effort ones warrant pushback.
Determine if the request is time-sensitive or blocks other critical work. If it's urgent and you can unblock quickly, drive it; if not, negotiate timing or ownership.
If pushing back, explain your reasoning with data and propose an alternative (e.g., a different approach, a later timeline, or another owner). If driving, clarify scope and success criteria.
After the decision, review outcomes to refine your judgment. Share learnings with the team to improve collective prioritization.

Went with a story about catching a flawed metric being used to justify a feature launch.
Choose a specific example where you used data to challenge a product decision or shape its direction, ideally one with measurable impact. Structure your answer using a clear narrative arc: context, your analysis, the insight, how you influenced stakeholders, and the outcome. Emphasize your role as a data scientist in driving evidence-based decisions and cross-functional alignment.
Pro tip: Quantify the impact of your intervention—e.g., 'prevented a feature that would have cost $X' or 'increased engagement by Y%'—and highlight how you navigated pushback with data and diplomacy. Show that you not only identified the issue but also collaborated to find a better solution.
Briefly describe the product decision, the team involved, and why it mattered. Provide enough context to understand the stakes without overwhelming with details.
Explain the data you analyzed, the methods you used, and the key insight that revealed the decision was flawed or needed redirection. Focus on your specific contribution.
Describe how you communicated your findings to product managers, engineers, or leadership. Highlight how you tailored the message to the audience and addressed concerns.
Share the result: what changed, how it affected metrics or user experience, and any lessons learned. Quantify the impact if possible.
