End-to-End Project Presentation + Deep-Dive Follow-ups

Instructions (10 minutes, max 5 slides)

Present an end-to-end project you led that shipped to real users. Assume the interviewer has not seen this work. You may anonymize sensitive details.

Your presentation should cover:

• Problem context and why it mattered.
• Stakeholder goals and success criteria.
• Data sources and instrumentation.
• Modeling/analysis approach and experiment design.
• Key product/engineering decisions.
• Results and trade-offs.

Then answer:

1. Which single metric did you optimize, which guardrails did you set, and why? Describe a time your chosen metric conflicted with another stakeholder’s metric and how you resolved it.
2. What went wrong? Provide one concrete mistake (e.g., incorrect metric trade-off or flawed assumption) and what you changed afterward.
3. If leadership rejects the proposal due to metric concerns (e.g., retention up but revenue down), propose a revised plan for a follow-up experiment or rollout that addresses the concerns without resetting timelines.
4. How did you collaborate with DE/PM/design? Provide a specific example of negotiating scope or data model changes under time pressure.
