Interview Prompt
We run data quality checks across our tables and want to see where they're breaking. For each table that had at least one failed check, show how many checks failed and the worst failure percentage among them, most failures first.
Summary
The tables that fail the most checks.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
