Interview Prompt

Our config parser validates template strings before deployment. Write a function called is_balanced that takes a string containing brackets and returns True if every opening bracket has a matching closing bracket in the correct order. The string may contain (), [], and {} pairs, plus other characters that should be ignored.

  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
