Interview Prompt
A linter for our query templates rejects expressions whose grouping symbols don't line up. Given a string `s` of parentheses, square brackets and curly braces, return `True` when every bracket is properly closed and `False` otherwise.
Summary
Every door you open is a promise to close it, in order.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
