Interview Prompt

Our search relevance scorer needs word frequency analysis with a singletons list. Write a function that takes a list of words and returns a dictionary with 'counts' (word → frequency mapping) and 'unique' (sorted list of words appearing exactly once).

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
