Interview Prompt

A regulatory audit requires cross-checking transaction records between two systems that should agree. Write a function that takes two record lists and an ID field, then produces a reconciliation report showing what's missing from each side, what matches, and where the field values disagree.

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
