Interview Prompt

The people analytics team is assembling a first-quarter department scorecard. Show each department's total payroll beside the combined Q1 metric value on record for that department.

Summary

Two tables know different things about the same people. Combine them.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
