FastAPI · interview question
A teammate submits shaky validation code. Which review comment is the strongest?
Multiple choiceMediumchapter-13-curatedpremiumfastapivalidation
Answer and explanation
Correct answer
C. Make the rule clearer and easier to explain. Reject bad requests before the workflow invests more state and side effects into them.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Allowing invalid data deeper into the service layer makes later failures harder to interpret.
