Short answer: Definition: A User Story describes a feature from the end-user’s perspective.

Explain a bit more

It answers: Who wants it? What do they want? Why do they want it? Template: As a [type of user], I want [some goal], so that [some reason]. Best practices: Add Acceptance Criteria to clarify expectations. Keep it concise, focused, and testable. Follow On: Example: As a shopper, I want to filter products by price range, so I can find items within my budget. Acceptance Criteria: Price slider from $0–$500 Real-time update of results Works on mobile and desktop

Real-world example (ShopNest)

“Add UPI” is a story with acceptance criteria. Points reflect effort/risk, not days on a calendar.

Say this in the interview
