Data science case study

Structure the ambiguity

A fitness app introduced a social feature where users add friends and share workout achievements. How would you quantify its impact on key company metrics?

1

Understand

Clarify the motivation for building the feature and the decision the team needs to make.

2

Measure

Define success metrics and the guardrails that would reveal unintended effects.

3

Recommend

Analyze the available evidence, separate causation from correlation, and make a clear recommendation.

Talk through your approach. Dawn AI follows up like a real interviewer.

From reading to interview-ready

Case interviews rarely have one correct answer. Build the habit of organizing ambiguity, choosing useful metrics, testing assumptions, and communicating a decision clearly.

Work through real cases

Practice product, retention, recommendation, pricing, and causal-inference scenarios similar to interview prompts.

Explain your thinking

Talk through your framework and respond naturally when the interviewer challenges an assumption.

Improve immediately
