Common question types

  1. Find top customers by revenue.
  2. Count orders by city, state, or channel.
  3. Join customers and transactions data.
  4. Calculate monthly growth using window functions.
  5. Find churn-risk users using recent activity logic.

How to answer well

State your approach first, then write the query. Mention assumptions, grouping logic, null handling, and why your answer matches the business question.
