Metrics Analysis and Data Driven Problem Solving Questions

Skills for using quantitative metrics to diagnose and solve product or support problems. Candidates should be able to identify relevant key performance indicators such as customer satisfaction, response time, resolution rate, and first contact resolution, detect anomalies and trends, formulate and prioritize hypotheses about root causes, design experiments and controlled tests to validate hypotheses, perform cohort and time series analysis, evaluate statistical significance and practical impact, and implement and monitor data backed solutions. This also includes instrumentation and data collection best practices, dashboarding and visualization to surface insights, trade off analysis when balancing multiple metrics, and communicating findings and recommended changes to cross functional stakeholders.

Write a SQL query that returns, for the last 12 weeks, daily WAU and MAU per week and the DAU/MAU ratio per week. Assume events(user_id, occurred_at) and that WAU is unique users in a calendar week. Use Postgres or BigQuery syntax and explain how you handle overlaps between DAU and MAU calculations.
