Product design question

What is acceptance criteria? What is it used for?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Foundational product management vocabulary and how it is applied in practice during feature delivery.

Define acceptance criteria clearly, the specific, testable conditions a feature must meet to be considered complete and correct.
Explain its purpose, aligning engineering, QA, and product on a shared definition of done before development starts.
Give a concrete example, e.g. for a login feature, criteria might include correct error messages for invalid credentials and a maximum load time.
Explain how it differs from a user story, the story describes the who and why, acceptance criteria defines the precise what and pass or fail conditions.
Explain when it's written, ideally during backlog refinement before a sprint starts, with input from QA and engineering.
Note its downstream value, reducing back and forth during QA and preventing scope disagreements at review time.

Gives a precise, testable example rather than a vague definition, e.g. specific error states and a load time threshold for a login feature.
Clearly distinguishes acceptance criteria from a user story, showing understanding of where each fits in the process.
Explains the collaborative process, involving QA and engineering early, not just the PM writing it alone.
Connects the practice to a concrete downstream benefit, fewer QA disputes and clearer sprint completion.

Giving only a textbook definition with no concrete example.
Confusing acceptance criteria with a user story or a full product requirements document.
Not explaining who is involved in writing it or when.
