What is a User Story, and how do you write effective User Stories? Definition:

Short answer: User Story describes a feature from the end-user’s perspective. It answers: Who wants it?

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

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
