Interview Prompt

Write a Python class called CharFrequency that accepts a string on initialization. It should have a method get_counts() that returns a list of (character, count) tuples sorted alphabetically by character. Spaces should be ignored.

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
