How do user personas and stories inform technical design and edge cases?
Tests if you translate product requirements into technical constraints and failure modes. Strong answers map persona pain points to architecture, derive unhappy paths from preconditions, and validate edge cases through vertical slices.
Tests whether you bridge product definition and system architecture using personas and stories. A strong answer extracts non-functional requirements from the persona like latency or accessibility needs, then maps each story to data models, APIs, and state machines while listing preconditions and triggers. It derives edge cases by asking what happens when preconditions fail, when stories interact, or when the user leaves the happy path. It should also mention vertical slicing so every story delivers end-to-end value and remains testable.
