Surface-level answers should be challenged with follow-ups like 'Can you explain the mechanism behind that?' or 'What trade-offs did you consider?' Do not accept buzzword answers — probe for concrete examples and implementation details. When a candidate mentions a pattern, ask them to describe a time it failed or they chose differently.
