FastAPI interviews without the guesswork.
FastAPI roles lean on async Python, typed validation and fast APIs, often in front of AI services. Interviews check whether you understand what async really changes and how to keep endpoints reliable.

One question.
See how you think.
This is the style of every question in the assessment: real situations, not trivia, with an explanation for each answer. The full test covers 28 questions across 7 skills.
A client sends a signup request with the email field missing. What should the API return?
Invalid input is the client's fault, so it is a 4xx. FastAPI returns 422 for validation errors by default; many teams use 400. Returning 200 for errors breaks clients and monitoring.
