Interview Prompt

Each store location collects customer reviews, and the product team wants to find the single most widespread piece of feedback across all locations. Given the review data, find which review appears in the most stores. If a store submitted the same review multiple times, it still counts as one store.

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
