FastAPI Explained | Mock Interview for FastAPI Developers | Senior Developer Interview Questions

Posted by



FastAPI is a modern, fast (high-performance), web framework for building APIs with Python which is particularly well suited for building APIs quickly and efficiently while still providing all the benefits of Python language. FastAPI is a popular choice among developers due to its speed, ease of use, and support for asynchronous programming.

In this tutorial, we will cover what FastAPI is, discuss some interview questions for senior FastAPI developers, and provide tips for a successful FastAPI mock interview.

What is FastAPI?

FastAPI is an open-source web framework for building APIs with Python. It is based on standard Python type hints, which provide type checking and validation at runtime. FastAPI is built on top of Starlette, a lightweight and flexible ASGI framework for building high-performance web applications.

FastAPI provides automatic validation, serialization, and documentation of API endpoints based on Python type hints. This makes it easy to build APIs quickly and efficiently while reducing the chances of errors in your code.

FastAPI also provides support for async/await, which allows developers to write asynchronous code that can handle many requests at the same time without blocking the execution of the program. This makes FastAPI well-suited for building high-performance APIs that can handle heavy traffic.

FastAPI Mock Interview

If you are preparing for a FastAPI mock interview, it is important to be familiar with the core concepts of FastAPI, as well as some common interview questions that may be asked. Here are some interview questions for senior FastAPI developers:

1. What is FastAPI and how does it differ from other web frameworks in Python?
2. What are the benefits of using FastAPI for building APIs?
3. How does FastAPI handle route validation and serialization?
4. How does FastAPI support asynchronous programming?
5. Can you explain the difference between request and response models in FastAPI?
6. How does FastAPI generate API documentation automatically?
7. How do you handle authentication and authorization in FastAPI?
8. What are dependency injections in FastAPI and how are they used?
9. How does FastAPI handle error responses and exceptions?
10. What tools and libraries can be used with FastAPI to enhance API development?

Tips for a Successful FastAPI Mock Interview

To have a successful FastAPI mock interview, it is important to be well-prepared and confident in your knowledge of FastAPI and web development concepts. Here are some tips for a successful FastAPI mock interview:

1. Review the FastAPI documentation and familiarize yourself with its core features and concepts.
2. Practice coding with FastAPI and build a few sample APIs to gain practical experience.
3. Be prepared to discuss your experiences with FastAPI and any projects you have worked on using FastAPI.
4. Be ready to answer questions about asynchronous programming, route validation, serialization, authentication, and error handling in FastAPI.
5. Practice discussing your problem-solving approach and how you would handle different scenarios in a FastAPI project.
6. Be confident in your knowledge of Python and web development best practices.

In conclusion, FastAPI is a powerful web framework for building APIs with Python, and a popular choice among developers for its speed, ease of use, and support for asynchronous programming. By familiarizing yourself with FastAPI concepts and practicing with sample projects, you can prepare for a successful FastAPI mock interview and demonstrate your expertise in building APIs with FastAPI.

This is how interviews should be. I really enjoyed the video.

How can someone with no industry experience but good at using FastAPI get a job on Turing?
