What kinds of questions might you be asked about Django?

Django interview questions may help the hiring manager figure out how well you understand web frameworks, how important Django is, and how good your coding skills are for the job of a developer. The interviewer will often ask about the real-world uses and applications of Django to find out how interested you are and how much experience you have. You can also expect the interviewer to ask you questions based on scenarios to test your ability to make decisions and your soft skills.

12 common interview questions about Django and some sample answers

Here are some questions that hiring managers often ask at interviews:

What is Django?

The interviewer might want to know how you feel about the Django framework as a whole. Try to answer the question from a broader point of view, talking about how Django can be used and how it compares to other options. To keep things short, you can answer in one or two sentences.

Example: “Django is a high-level web framework built on Python that lets you build websites quickly and with lots of features. It is open-source and free.”

Why would you want to use Django?

During a Django interview, this is one of the most basic questions the interviewer asks. You could talk about the benefits of using Django in real life. You can also talk about what a developer or organization can get out of it.

Example: “Python is used to write Django, and Python is a great, clean, easy-to-learn programming language that is taught by many schools. It lets developers work quickly because it has a lot of features and functions, such as support for multiple sites and languages, asynchronous JavaScript and XML (AJAX) support, application programming interfaces (APIs), and object-relational mapping (ORM). Django also has clear instructions and documentation.”

Describe how Django is put together.

This question is meant to find out how much the candidate knows about architectural patterns. Think about writing a short description of each part of the building. This can show the interviewers that you know how to use the term in different contexts.

Example: “The Model-View-Template (MVT) architecture is what Django is built on. MVT is a software design pattern used to make a web app. The model helps in database management. It has a layer that lets you access the data. The Template is a presentation layer that handles the whole user interface, and the View is used to send data, render a template, run business logic, and interact with a model.”

Why do web developers like Django so much?

The ability to understand the reasoning behind any specific choice is a key skill for a team leader or project manager. This question allows you to explain your unique perspective on Django. Try to stick to web developers when making your points.

Example: “Django has a framework that is designed to automatically do the things that are needed to keep a website safe. This helps developers avoid many common security mistakes. Programming for Django is done with design principles and patterns in mind. This makes it easy to maintain and reuse the code. It also has a large, helpful community that web developers can reach through a number of forums, channels, and websites that are just for them.”

How do you find out which version of Django is on your computer?

Such technical questions check to see if you know the basics of how to work with Django. Include the exact command you type to find out about the version. When asked this kind of question, try to keep your answer short.

“To find out what version of Django is on a system, open the command prompt or terminal and type py-m Django —version. You may get back information about the Django version you have installed.”

What does “Django exception” mean?

This is a concept-based question that the interviewer may use to test how well you know how to debug and handle errors in Django. You can use this question to show that you know how important it is to write code that is easy to read and has good error-handling functions. Start your answer by giving an explanation of the exception.

Example: “An exception is something that happens while a program is running that stops the instructions from going in the usual order. Django comes with a number of built-in exception packages that a programmer can use to get meaningful errors that make debugging easier. If a developer is working on a big project, he or she may decide to make custom exceptions that can tell exactly what went wrong.”

What does CRUD mean?

This is another question that tests how well you know the basic terms used in software development. You can start by saying what CRUD stands for, then talk about how it is used in general, and then give an example.

Example: “CRUD is an acronym for creating, reading, updating, and deleting. These are the four most common things a model can do. One of the first things that developers do is make a CRUD application. As a way to build a Django web application, we can talk about CRUD. Most of the applications on the internet are CRUD apps. For example, a social media site can save your information on its database by using CRUD operations. When you change your profile picture, you are updating your profile.”

Is Django a content management system (CMS)?

Sometimes this is a trick question. If a candidate doesn’t know enough about Django and CMS, they might give answers that are wrong or don’t cover everything. Start your answer by giving a clear description of Django and CMS.

Example: “No, Django is not a content management system in and of itself. It’s just a web framework that helps make websites that work well. A CMS is a program that is used to manage the content on a website and lets many people create, edit, and publish content. A CMS can be made with Django. In fact, a CMS called Django CMS is based on it.”

Tell me what Middleware is and how it works in Django.

This is a basic concept-based question that could help the interviewer figure out how much you know about Django in general. A good answer might start with a definition of Middleware and a list of its most important tasks.

Example: “Middleware in Django are small plugins that run in the background while the request and response are being processed. You can automate tasks with the help of middleware. Some of the most important things that middleware does are related to security, sessions, and authentication.”

What versions of Python can be used with Django?

With this question, the interviewer can see how well you pay attention to details. Version numbers are often forgotten, which can make it hard for things to work together. You can talk about the version details of the most recent version first, then talk about what it does for you.

Example: “Even though you can use older versions of Python, the latest Django version 3.2 works best with Python 3.6 or higher. Python 3 has more features, better support, and runs faster.”

Is Django better than Flask?

With these kinds of questions, the interviewer tries to find out if the candidate is interested and if they know about similar options. When you answer such a question, make sure to back up your point with good reasons. A good answer would tell the difference between the two and say what the best use for each is.

Example: “Django is a full-stack web framework that follows the batteries-included approach, whereas Flask is a lightweight framework with minimalistic features. From a learner’s point of view, Django is complicated, huge, and has a steep learning curve. Flask, on the other hand, can be a good place to start if you want to learn how to make websites. Both frameworks have their own best use cases. For example, Django is best for a large, complex web app that doesn’t need new features all the time. Flask is better for small web apps that are always changing because it gives you the freedom to add new features quickly.”

What does the Django command “migrate” do?

Migration is an important part of making any kind of software. If you have questions about migration, check to see if you have worked with Django before. Try to say exactly what the command does, and then say a little more about how it works.

Example: “The’migrate’ command creates a table based on the schema in the migration file. Migrations are how Django tells your database schema about changes you make to your models, like adding or removing fields or models. For each model, it makes a migration file in the migration folder to create the table schema, and each table is linked to the model for which the migration was made.”
