A client asks how Salesforce can integrate with their existing marketing and finance systems. How do you explain the options?

I would first clarify the data flows: which system is the source of truth, what data moves, how often, and in which direction. Then I outline options: standard APIs such as REST and Bulk for data exchange, event-driven approaches like platform events and Change Data Capture, middleware such as MuleSoft for orchestration, and prebuilt connectors or AppExchange products.

The recommendation depends on volume, latency, reliability needs, budget and in-house skills.

The interviewer wants a requirements-led explanation rather than a product pitch. Good answers mention system of record and data ownership. A pitfall is recommending a specific tool before understanding the data flows.
