Scenario

You're responsible for a business-critical pipeline that keeps customer and revenue data aligned across two core systems. A sync breaks, records drift apart, and teams start seeing conflicting account ownership, lifecycle stage, and opportunity data. You need to figure out whether the issue came from extraction, transformation logic, load behavior, scheduling, or a schema or API change.

Question

Tell me about a time a critical sync between HubSpot and Salesforce broke. How did you diagnose and resolve it?
