Data Driven Recommendations and Impact Questions

Covers the end to end practice of using quantitative and qualitative evidence to identify opportunities, form actionable recommendations, and measure business impact. Topics include problem framing, identifying and instrumenting relevant metrics and key performance indicators, measurement design and diagnostics, experiment design such as A B tests and pilots, and basic causal inference considerations including distinguishing correlation from causation and handling limited or noisy data. Candidates should be able to translate analysis into clear recommendations by quantifying expected impacts and costs, stating key assumptions, presenting trade offs between alternatives, defining success criteria and timelines, and proposing decision rules and go no go criteria. This also covers risk identification and mitigation plans, prioritization frameworks that weigh impact effort and strategic alignment, building dashboards and visualizations to surface signals across HR sales operations and product, communicating concise executive level recommendations with data backed rationale, and designing follow up monitoring to measure adoption and downstream outcomes and iterate on the solution.

Explain precision and recall in the context of a fraud detection model used by operations. Provide examples of business costs related to low precision vs low recall, and how you would set operating thresholds based on those trade-offs.

Behavioral: Tell me about a time when you had to present a data-driven recommendation to senior leadership with limited time. Describe how you structured the message, chose which analyses to include, and how you handled questions you couldn't fully answer in the moment.

You have a table `events(user_id, event_name, event_time)` and `users(user_id, signup_date)`. Write a SQL query (ANSI SQL) to compute weekly Active Users (WAU) and week-over-week percent change for the last 12 weeks. Include handling of weeks with zero activity so that percent change doesn't divide by zero and explicitly show column names.

Executive-summary case study: Given this short result (numbers hypothetical): 'A/B test on checkout flow → Treatment lift in conversion +3.2% (p=0.04), average order value -1.0% (p=0.20), 14-day retention +0.5% (p=0.30)'. Write a concise 3-bullet recommendation for the CEO that quantifies expected impact at scale (use provided numbers), states key assumptions, and proposes a 90-day rollout plan with success criteria.

You must recommend whether to launch a 30-day free trial nationally. Your model predicts 3 scenarios: conservative (net profit +$100k), expected (+$300k), optimistic (+$600k) over 12 months with probabilities 0.2, 0.6, 0.2 respectively. Compute expected value, describe decision rules you might propose to leadership, and propose two risk mitigations if actual results trend toward the conservative outcome.
