Interview Prompt
We're compiling a leaderboard for the onboarding_v3 experiment, where a user's standing is the total metric value they drove. Return the users in the top ten standings, biggest first, along with the variant each was assigned.
Summary
In every experiment, a handful of users carry the result. Find them.
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
