Interview Prompt

HR wants to know which job titles are held by the company's highest earners. You have two datasets: worker records and title records, linked by worker_id. Find every title held by someone earning the top salary. Return unique titles only.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
