Interview Prompt

Given a list of words, group them by their unique character sets - words that contain exactly the same set of distinct characters should be placed in the same group. Return the groups as a list of lists. Order within groups and order of groups does not matter.

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
