Interview Prompt
We need to pull data from a third-party project management SaaS API - tasks, users, and projects - and land it in our data warehouse for analytics. The API doesn't push events; we have to poll it. Design a connector that keeps our warehouse in sync incrementally, handles schema changes as the vendor evolves their API, and stays within rate limits.
Summary
The API gives you 100 records at a time. You need millions.
