Interview Prompt

Our marketplace ranking algorithm prioritizes listings with the most reviews. Write a function called most_reviewed that takes a dictionary mapping names to lists of review scores, and returns the name with the highest review count.

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
