Django is a batteries-included Python web framework, and its interviews test the MVT architecture, the ORM (its biggest feature), models and migrations, and the request-response cycle. Here are the Django interview questions that actually get asked, with answers. (See also our Python guide.)
Architecture
- What is the MVT (Model-View-Template) pattern, and how does it differ from MVC?
- The Django request-response cycle.
- What is middleware and where does it run?
- URL routing and the role of views.
The ORM (the core)
- What is the Django ORM and QuerySets?
- QuerySets are lazy — what does that mean?
- The N+1 query problem; select_related vs prefetch_related.
- Migrations — makemigrations vs migrate.
- Model relationships — ForeignKey, ManyToMany, OneToOne.
Features & security
- Django REST Framework basics — serializers, viewsets.
- Authentication and the user model.
- CSRF protection; how Django handles it.
- Signals; caching options.
How to prepare
Django rounds probe the ORM and request flow. Practise explaining QuerySets and the N+1 fix out loud. Greenroom runs spoken technical interviews that follow up on your reasoning. Pair it with our Python and backend guides.
Frequently asked questions
What are the most common Django interview questions?
Common Django questions cover the MVT architecture and how it differs from MVC, the request-response cycle and middleware, URL routing and views, the ORM (QuerySets, laziness, the N+1 problem, select_related vs prefetch_related), migrations, model relationships, Django REST Framework, authentication, and CSRF protection.
What is the difference between MVT and MVC?
Both separate concerns, but Django's MVT (Model-View-Template) maps roughly to MVC with different naming: the Model is the data layer, the Template is the presentation layer (like the View in MVC), and Django's View contains the business logic that connects them (like the Controller). Django itself handles much of the controller routing, so the framework fills that role.
What is the N+1 query problem in Django?
The N+1 problem occurs when you fetch a list of objects (1 query) and then access a related object for each one in a loop, triggering N additional queries. In Django you fix it with select_related (a SQL join for ForeignKey/OneToOne) or prefetch_related (a separate query for ManyToMany/reverse relations), reducing many queries to a couple.
How should I prepare for a Django interview?
Focus on the ORM — QuerySet laziness, the N+1 problem and its fixes, migrations and model relationships — plus the MVT architecture and request cycle, since these distinguish real Django experience. Practise explaining the ORM and request flow out loud with a voice-based mock interview that follows up, because Django rounds are conceptual and verbal.
