Analyze KPI Drop: Immediate Steps for Stakeholder Persuasion
Overview
This question evaluates a data scientist's ability to persuade stakeholders with evidence while rapidly diagnosing and communicating about a sudden KPI drop, testing competencies in data-driven influence, product-metrics analysis, and cross-functional leadership within the Behavioral & Leadership category.
Behavioral + Mini-Case: Persuading with Data and Responding to a KPI Drop
Context
You are a Data Scientist interviewing onsite for a role focused on product/business impact. The interviewer wants to assess your ability to influence stakeholders using data and your structured response to a sudden metric decline.
Assumptions for the mini-case:
- Critical KPI example: Checkout conversion rate (but you may choose another meaningful product KPI).
- “20% drop” is a relative decline over the past 24 hours versus a recent baseline (e.g., 7-day hourly average), unless you clarify otherwise.
- Time constraint: Outline what you would do in the first 60 minutes.
Part A — Behavioral (STAR)
Tell me about a past experience where you had to persuade stakeholders with data. Use the STAR framework (Situation, Task, Action, Result). Highlight how you diagnosed the problem, aligned incentives, handled objections, and communicated clearly to drive a decision.
Part B — Mini-Case
Yesterday a critical KPI suddenly dropped 20%. What are your first steps within the next hour? Demonstrate a structured diagnosis and communication plan.
