Your question is Design for Cross-Platform Reliability. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about how you ensure reliability and observability when building features that integrate across different platforms at Salesforce.
Discuss how you would design integration boundaries, validate data and model behavior, monitor dependencies, and respond to failures. Explain how you would detect training-serving skew, feature drift, partial outages, and degraded downstream platforms without exposing customer data.
