Interview Prompt

We run data quality checks against various tables. For each table, show the count of failed checks (where passed is false) and the highest failure percentage among those checks. Rank sorted from most failures to least, and skip tables with zero failures.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
