Interview Prompt
Before deploying a config template, the CI pipeline validates that all bracket pairs are properly matched. Mismatched brackets in JSON or YAML templates have caused production outages before. Write a function that checks whether all parentheses, square brackets, and curly braces in a string are properly balanced and nested, ignoring all other characters.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your python solution with real code execution
- Get instant feedback and a hire/no-hire decision
