About This Test

This assessment prepares you for common Django questions asked during technical interviews.

This test covers interview-focused Django topics that employers consistently ask about. You'll practice answering questions that evaluate both your technical knowledge and your ability to communicate solutions clearly.

Questions simulate real interview scenarios with emphasis on explanation and justification. Each question requires you to not just identify correct answers but understand the reasoning behind Django's design decisions.

Use your results to practice articulating Django concepts in interview settings. Review explanations for each answer to develop confident, thorough responses for your next technical interview.

What This Test Covers

MVT Architecture

Explaining Django's model view template pattern and how it differs from classic MVC.

ORM Depth

QuerySet laziness, select_related versus prefetch_related, and avoiding common query pitfalls.

Request Flow

How a request travels through URLs, middleware, views, and templates to a response.

Built-in Features

The admin, authentication, forms, and migrations that ship with Django.

Sample Questions

A few real questions from this test, with answers and explanations. Take the full test above for the complete set.

Django QuerySets are lazy. When is the database query actually executed?

Answer: Only when the QuerySet is evaluated, such as by iterating, slicing with a step, or calling list()

Building and chaining a QuerySet issues no SQL. The query runs the first time the results are needed, for example on iteration, list(), len(), or bool() evaluation.

After a QuerySet is evaluated once and stored in a variable, what happens when you iterate it again in the same scope?

Answer: It reuses the cached results without hitting the database again

A QuerySet caches its results after the first evaluation, so re-iterating the same object uses the cache. Calling filter() again or re-creating the QuerySet, however, produces a fresh query.

The N+1 query problem in Django typically appears when you:

Answer: Loop over objects and access a related object per iteration without select_related or prefetch_related

Iterating a list of objects and touching a related row each time issues one extra query per object, the classic N+1 pattern. select_related or prefetch_related collapses those into far fewer queries.

What best describes Django middleware?

Answer: Layers of hooks that process every request and response globally

Middleware are components in a request-response pipeline that can inspect or modify each request on the way in and each response on the way out. Authentication, sessions, and CSRF protection are implemented as middleware.

One key advantage of class-based views over function-based views is that they:

Answer: Promote reuse through inheritance and mixins for common patterns

Class-based views let you compose behavior with mixins and inheritance, so shared patterns like list, detail, and form handling are reused rather than repeated. Function-based views are simpler but tend to duplicate logic.

Frequently Asked Questions

Find answers to common questions about this assessment

MVT stands for model, view, template. The model defines data, the view contains logic that processes requests and fetches data, and the template renders the response. It resembles MVC, but Django's view plays the role of the controller, and the template is the view layer. The framework itself handles routing between them.

select_related uses a SQL join to fetch related objects in the same query, best for foreign key and one to one relations. prefetch_related runs a separate query and joins results in Python, needed for many to many and reverse foreign key relations. Both reduce the number of queries when accessing related data.

A request first passes through configured middleware, then Django matches the URL to a view. The view runs logic, often querying models through the ORM, and returns a response, frequently by rendering a template with context. The response travels back through middleware before reaching the client. Understanding this flow explains where to add logic.

Django is batteries-included, shipping an admin interface, an authentication system, forms handling, an ORM with migrations, and protections against common attacks like CSRF and XSS. This lets you build full applications quickly without assembling many separate libraries, which is a key reason teams choose the framework.

Review core Django topics: the request and response cycle, the ORM and QuerySets, models and migrations, views, templates, and forms. Practice explaining middleware, signals, and how the admin works. Be ready to discuss security features, caching, and REST APIs with Django REST Framework. Build or review a small project so you can talk through real design decisions you made.

Python and Django interviews often share fundamentals, so revise Python data structures, list comprehensions, decorators, generators, and how mutable defaults behave. On the Django side, connect that Python knowledge to the ORM, class-based views, and custom managers. Interviewers may ask about testing, virtual environments, and packaging, so being fluent in Python basics strengthens your Django answers.
