Interview Prompt
Our automated data-quality suite writes one row per check it runs, and we're tracking where records are breaking. For each table with failing checks, report how many checks failed and how many of those were critical or high severity.
Summary
Every dataset has a weak point. Surface the ones the checks already caught.
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
