Interview Prompt
You're building a data-lineage tool that needs to know which tables each query reads. Given a SQL query string `sql`, pull the table names that follow its FROM and JOIN keywords, where a name may be trailed by an alias that isn't part of it.
Summary
Somewhere in that query, tables are hiding.
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
