Behavioral Prompt: 2–3 Minute Project Walkthrough (Data Scientist, Technical Screen)

Deliver a concise, 2–3 minute walkthrough of the single most impactful project you led end-to-end. Use clear, scannable structure and concrete numbers. If exact figures are confidential, provide order-of-magnitude or use absolute percentage points (pp) with sample sizes.

Address all of the following:

1. Problem statement, business context, and exact timeframe
2. Your role, stakeholders, and team size
3. Baseline metrics, target metrics, and final measured impact with concrete numbers
4. Two alternative approaches you explicitly rejected and why
5. The hardest trade-off you made (e.g., speed vs. quality; scope vs. reliability) and how you justified it to stakeholders
6. One major risk or unknown you de-risked (how you measured it and what would have changed if your assumption was wrong)
7. A conflict or pushback you faced and how you resolved it
8. What you would do differently if you had to redo it next quarter and why
