6. Common Python Django Developer Interview Questions

1. “What is Django, and why is it used?”

The interviewer is trying to determine your understanding of Django’s purpose and key advantages.

Example Answer

• “Django is a high-level Python web framework designed to enable rapid development of secure and scalable web applications. It promotes a clean, pragmatic design and comes with built-in features like ORM, authentication, and admin interfaces. Django’s simplicity and ‘batteries-included’ philosophy make it ideal for building robust web applications efficiently.”

2. “Explain Django’s MVT architecture.”

This question is asked to test your understanding of Django’s architecture and its workflow.

Example Answer:

“Django follows the MVT (Model-View-Template) architecture:

• Model: Handles data and defines the structure of the database.
• View: Contains the logic to handle user requests and retrieve data from the model.
• Template: Handles the presentation layer, rendering dynamic HTML pages based on data passed by the view. MVT separates concerns, making development easier and more maintainable.”

3. “How do you create a project and an app in Django?”

This questions tests your familiarity with Django’s project and app structure.

Example Answer:

“To create a Django project, I use the command: django-admin startproject project_name.

This sets up the project structure, including settings, URLs, and the WSGI file.

To create an app, I navigate to the project directory and run: python manage.py startapp app_name.

This generates a folder for the app with its models, views, and other components, which can then be included in the project by adding the app to the INSTALLED_APPS list in the settings file.”

4. “What is ORM, and how does Django implement it?”

Used to test your understanding of ORM and its advantages.

Example Answer:

“ORM (Object-Relational Mapping) is a technique that allows developers to interact with a database using Python objects instead of SQL queries. Django implements ORM through its models, where each model corresponds to a database table. For example, using Django ORM, I can perform queries like MyModel.objects.filter() to fetch data without writing raw SQL.”

5. “What are middleware in Django?”

What They’re Looking For:

Your understanding of middleware and its role in the request-response cycle.

Example Answer:

• “Middleware in Django is a framework of hooks used to process requests and responses globally before they reach the view or after the view processes them. For example, middleware can handle authentication, session management, and modifying request headers. Some default Django middleware includes AuthenticationMiddleware, SessionMiddleware, and CsrfViewMiddleware.”

6. “How does Django handle static files?”

Your ability to manage static resources in a Django application.

Example Answer:

• “Django uses the STATIC_URL setting to define the URL path for static files and the STATICFILES_DIRS setting to specify the directories containing static assets. During development, Django serves static files automatically. For production, I use the collectstatic command to gather all static files into a single directory for efficient deployment.”

7. “How do you create a custom model in Django?”

What They’re Looking For:

Your ability to define and work with models in Django.

Example Answer:

“To create a custom model in Django, I define a class in the models.py file that inherits from django.db.models.Model. For example:

(add )
