Interview Prompt
Operations wants to compare how cleanly each region closes out orders. For each region, give the share of its orders that reached 'Completed' status, as a percentage.
Summary
Not every region closes orders cleanly. The percentages tell the story.
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
