Service Design · interview question
A teammate submits shaky dto mapping code. Which review comment is the strongest?
Multiple choiceHardchapter-12-curatedpremiumservice-designdto-mapping
Answer and explanation
Correct answer
C. Make the rule clearer and easier to explain. Use boundary objects when the partner payload shape is not the shape the rest of your code wants to reason about.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Skipping DTOs can make the service layer speak in partner-specific language forever.
