Top Django Interview Questions & Answers (2025)

If you’re interviewing for a Django developer, backend engineer, or full-stack Python role, mastering Django is essential. This guide covers 50+ top Django interview questions, complete with detailed answers, best practices, and insights into modern features—plus how to integrate Armenian text to speech into your Django app!


📈 Why Django Is Crucial for Developer Interviews

Django is a full‑featured, high‑level Python framework loved for its:

Employers rely on Django for robust, scalable, and secure web apps—so your Django skills need to stand out!


🧩 Beginner-Level Questions

1. What is Django?

A high‑level, open‑source Python web framework following the Model‑View‑Template (MVT) pattern. It emphasizes rapid development, reusability, and security.

2. What’s the difference between a Django project and an app?

A project is the whole configuration; an app is a modular sub‑component (e.g., blog, payments). Projects can contain multiple apps. Simplilearn.com

3. Explain the MVT architecture.

4. How do you create a Django model?

Use Python classes inheriting from models.Model, define fields (e.g., CharField, ForeignKey), then run makemigrations and migrate.

5. How do you map URLs in Django?

Define patterns in urls.py, using path() or re_path() to link URLs to views.


🛠 Intermediate-Level Questions

6. Explain Django’s ORM vs. raw SQL.

Django ORM abstracts SQL with Pythonic queries (e.g., User.objects.filter(...)) while still supporting raw SQL when needed.

7. How do you use the admin interface?

Register the model in admin.py (e.g., admin.site.register(MyModel)) to expose it with list and CRUD operations.

8. What’s a Django signal?

A way to trigger actions on events (e.g., pre_save, post_delete). Useful for logging or async tasks.

9. How does form validation work?

Use forms.Form or forms.ModelForm classes with validators and is_valid() checks. Automatically correct and sanitized via cleaned_data.

10. How do you serve static and media files?

Set STATIC_URL and STATICFILES_DIRS for static assets; MEDIA_URL and MEDIA_ROOT for uploads. In production, often served via Nginx or AWS S3. WebAsha


🚀 Advanced-Level Questions

11. What’s new in Django 4.2 LTS?

12. How do you use async views in Django 4.?

Define views with async def, and Django will handle them asynchronously (behind ASGI). Ideal for I/O bound tasks. WebAsha+15Django Project+15B-List+15

13. What is the new STORAGES setting in 4.2?

A unified setting for file storage backends (e.g., default, staticfiles) replacing older DEFAULT_FILE_STORAGE. Django Project

14. How do you implement REST API endpoints?

Typically via Django REST framework (DRF), with serializers and APIView or viewsets routed via DefaultRouter.

15. What are migrations?

Python scripts for schema changes. Use makemigrations to generate and migrate to apply to the DB.


🧠 Performance, Security & Architecture

16. How do you optimize query performance?

  • Use select_related/prefetch_related
  • Avoid N+1 queries
  • Add indices via db_index=True

17. How do you cache in Django?

Use caching backends like Memcached or Redis with decorators like @cache_page.

18. How to mitigate CSRF attacks?

Include {% csrf_token %} in forms. Django’s middleware enforces protection which rejects missing tokens.

19. How to use Django for async tasks?

Design background tasks via Celery or Django-Q, triggered by signals or ht tp requests.

20. Describe deployment best practices.

Use Gunicorn + Nginx behind an ASGI/WSGI server. Use HTTPS and environment separation (.env, .secret).


🧪 Scenario-Based and Behavioral Questions

21. Describe handling missing templates.

Django raises TemplateDoesNotExist; set custom handlers or log for debugging.

22. How do you handle file uploads safely?

Validate file types and sizes, store outside doc roots, randomize filenames, use virus scanning if needed.

23. Explain upgrading from Django 3.2 to 4.2.

Gain LTS with improved async, timezone, and ORM support—no code changes, but benefits apply automatically. Medium

24. How to implement pagination?

Use Paginator(queryset, per_page) then pass pages to the template.

25. What’s signal vs callback distinction?

Signals broadcast to multiple receivers globally, callbacks are defined within single classes or functions.


🗣️ Integrating Armenian Text to Speech

For apps targeting Armenian users (e.g., news portals, e-learning, accessibility features), integrate Armenian TTS by:

  1. Calling services like Google Cloud TTS with Armenian locale
  2. Serving audio via Django views or static URLs
  3. Caching audio in models or storage backend
  4. Exposing TTS buttons in front end for playback

This enhances UX and inclusivity in multilingual apps.


✅ Benefits of Using Django

  1. Rapid development using built-in tools
  2. Clean, scalable architecture with MVT
  3. High security by default
  4. Strong developer ecosystem (DRF, Channels)
  5. Scalable via async and task queues
  6. Built-in admin for easy content management
  7. Internationalization and localization features
  8. Long-term support versions like 4.2 LTS
  9. ORM simplifies database handling
  10. Accessible multilingual features like Armenian TTS

❓ Django Interview FAQ

1. Is Django still relevant in 2025?

Absolutely—especially with Django 4.2 LTS and its async, ORM, and storage improvements GitHub+1WebAsha+1CodefinityWebAsha+2Simplilearn.com+2Wikipedia+2Django Project+5Medium+5Medium+5

2. What Python versions does Django support?

Django 4.2+ supports Python 3.8+, with 4.2 introducing support for 3.11 and 3.13 compatibility

3. Should I learn REST framework or async first?

Start with REST (widely used), then expand into async once comfortable with core HTTP and view logic.


🧭 Final Thoughts

This guide covers the essentials—from beginner to advanced—preparing you to confidently answer Django interview questions. Know your models, views, admin, REST, async patterns, and deployment best practices.

And if you’re building multilingual apps, don’t forget to explore Armenian TTS integration for improved accessibility.
