What’s inside
- The Arena Score. 20 questions in 75 minutes: 8 SQL, 6 Excel, 4 AI-copilot and 2 judgment cases. A score out of 100, a level from L1 to L5, and an opt-in leaderboard. Free, once a week.
- Practice cases. Five product-analytics SQL cases set inside Kestrel, a made-up Indian investing app with a realistically messy database. Unlimited tries, hints and explanations.
- The course. 58 lessons in six gauntlets on the same skills as the test, each with a worked answer. The first lesson of every gauntlet is free.
SELECT step_order, step_name, users, pct_of_signups, pct_of_previous FROM counts ORDER BY step_order;

These five are a sample. The Product Analytics Casebook has 40.
Same company, same dataset, same grader. The other 35 cases go further into cohorts, experiments, TAT and SLAs, revenue and data quality. They also connect: the bug you find in one case explains the dip in another.
- 40 cases, each with the stakeholder’s ask, an exact spec and hints
- An answer key with reference SQL, the result, what it means, common mistakes and interviewer follow-ups
- The full Kestrel dataset (DuckDB and Parquet) with the offline grader
- An AI mock interviewer, so you can practise explaining your answers out loud
