Kısa yanıt

The FastAPI test is an intermediate, 10-minute assessment of practical judgment when building web APIs. Its 15 multiple-choice questions use short Python code and requests to examine route behavior, data checks and responses, middleware, and dependency resolution. It is for API and server-side engineers, full-stack engineers on Python back ends, and Python programmers moving into web work.

Ölçtüğü şey

Practical FastAPI knowledge: routing requests, checking and shaping data, middleware and dependency injection.

Routes, parameters and responses

Assess how a request is matched to a route, how parameters are handled, and what response the app returns.

Request and response models

Check how the app uses models to check incoming data and shape its response.

Middleware

See how middleware wraps a request as it moves through the app.

Dependency injection

Assess how the app resolves dependencies while handling a request.

Question formats

Multiple choice

The candidate: Reads a short situation, table or statement and picks the right answer, or every right answer.

You see: Whether the candidate knows the material well enough to apply it, not just recognize it.

15 questions in 10 minutes, served one at a time.

Roles this test fits

Engineers who write or maintain Python web services: API and server-side engineers, full-stack engineers working on a Python back end, and Python programmers moving into web work.

Evidence beyond a resume

See request-handling judgment
Short Python examples ask candidates to work out which route handles a request and what the app returns, showing practical code-reading judgment.
What happens to incoming data
Questions on request and response models show whether a candidate can predict what FastAPI checks in a request and what shape the reply takes.
Keep the questions focused on skill
Examples use neutral items, orders and bookings, with plain English and no idioms or local knowledge, so the questions focus on FastAPI behavior.

Test integrity signals for review

Each candidate gets a different set of questions, in a different order, with shuffled answer options. The browser shows one question at a time, and the test does not allow going back to earlier questions. Timing runs on the server; reloading restores the same question with only the time left. Answer keys stay on HireValid’s servers. HireValid records signals such as time away from the test tab, pastes into answers and unusually fast answers, then summarizes them in an Integrity Score and evidence timeline for the employer to review. It never decides on its own. With candidate consent, an employer can add webcam photos at random moments. Learn more about how we build our tests.

Use the score as one signal

Review the FastAPI score as evidence, not as a hiring decision. Pair it with a work sample in which the candidate explains what an API does with a request, including how data is checked and returned. Then use the same structured interview questions for each candidate. The pre-employment testing guide offers more context. For a related Python web framework, see Django.

Yapılandırılmış mülakat soruları

How would you trace a request that reaches an unexpected route in a FastAPI service?
Listen for a clear way to follow the request, check route matching and parameters, and explain the response.
A request passes through middleware but returns unexpected data. How would you investigate?
Look for a step-by-step approach that considers middleware flow, data checks and response shaping.
How would you debug an API call when a needed dependency is not resolved as expected?
Listen for how they would inspect the request handling and explain where dependency resolution fits into the call.

Understand scoring and benchmarks

Fairness and accommodations

Questions are about code behavior, not trivia or memorized version numbers, and each code sample uses neutral examples such as items, orders and bookings, with names from many backgrounds and no idioms, money symbols or local knowledge. English is kept plain so the test measures FastAPI skill rather than reading speed, and every question gets the same time.

You can give any candidate extra time as an accommodation. Results are evidence for a person to review, never an automatic decision.

Provisional: reliability is reported once 200 candidates have completed it.

Test details

A short, timed set of questions on building web APIs with FastAPI. Most questions show a few lines of Python and ask what the app does with a given request: which route answers, what gets checked and returned, how middleware wraps the call, and how dependencies are resolved. It looks at the practical judgment a developer uses when writing and debugging a FastAPI service.

Questions are in English.
No aids are needed.
Each question is answered once, in order, with no going back.
4 practice questions, 4 minutes, before the timed test.

Sık sorulan sorular

Which roles fit the FastAPI test?+

It is intended for engineers who write or maintain Python web services, including API and server-side engineers, full-stack engineers working on a Python back end, and Python programmers moving into web work. The test is intermediate, so consider whether that level fits the role you are hiring for.

What practice is available for the FastAPI test?+

Candidates can try a practice set of 4 questions in about 4 minutes before the test. It shows the format: a few lines of Python and a request, with a question about what the app does next.

How does the FastAPI test keep questions focused on job skill?+

Questions ask about code behavior rather than trivia or memorized version numbers. Examples use neutral items, orders and bookings, and plain English without idioms or local knowledge. Every question gets the same time, helping the test focus on FastAPI skill rather than reading speed.

What aids can candidates use in the FastAPI test?+

No aids are needed. The 15 questions come one at a time and in order, and candidates cannot go back to an earlier question, so each answer is settled before the next request is shown.
