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