3. How would you write user stories and acceptance criteria for a technical feature such as an API integration?

Why they ask: They check whether you can bridge business need and technical detail.

A sample answer to question 1

How do you gather and document requirements for a new system, and which techniques do you use?

I begin by identifying stakeholders and understanding the business problem and objectives, usually through a stakeholder map and a short scoping workshop. I then use a mix of techniques: one-to-one interviews for detail, workshops for alignment, observation of users doing their real work, and document analysis of existing processes and system data. I record findings as process maps in BPMN, user stories with acceptance criteria, and where needed a more formal requirements specification split into functional and non-functional requirements. Each requirement is uniquely numbered, prioritised using MoSCoW and traced to a business objective in a traceability matrix held in Jira or Confluence. I validate with stakeholders through walkthroughs before sign-off and keep a change log so scope movements are visible. The aim is requirements that are clear, testable and agreed, not just a long list.

Common mistake to avoid: Relying on one workshop only; Writing vague requirements like 'fast'
