A text column profiling job builds a character-frequency map to detect encoding anomalies. Return a dict mapping each character in the string to how many times it appears.

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
