Interview Prompt

We have a table of employee metric records, each carrying a numeric value. Find every way to pick three separate records whose values add up to exactly 25, and return the three values from each combination.

Summary

Pick three. See what they add up to.

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
