About the Flask test

Flask is one of the most popular web frameworks in Python, which makes it a very desirable skill for a Python web developer. Flask is more precisely known as a micro-framework because it lacks many dependencies and is quite lightweight. This makes Flask a very good option to create fast and concise web applications in a short time. As a Python framework, Flask opens the door to third-party libraries that also work seamlessly with its ecosystem, so the expandability and scalability of Flask is a big strength.

This hiring test is designed to evaluate Flask developers of intermediate level (two to three years’ experience) on their skills using Flask features and functionality in typical real-world scenarios. This screening test includes topics like APIs, intermediate database queries, intermediate routing endpoints, encryption and decryption of data, complex template functionality (Jinja2), and other specific Flask features. This Flask test also includes a section on deployment and testing—both vital skills for an intermediate Flask web developer.

Candidates who perform well on this test will have a strong grasp on web development using Flask and should be capable of using Flask tools and features with great proficiency and output efficiency, with clean code using RESTful principles.

Review from G2

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.
