Interview Prompt

The data platform team wants to see how many rows each batch job processed on its very first run, as a baseline for measuring throughput improvements over time. Show the job name and rows done from that first execution.

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 sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
