About the Object oriented programming test

Object oriented programming (OOP) provides a paradigm for designing code that is flexible, modular and abstract. Hiring developers who are well versed in OOP allows your business to build programs efficiently, while providing speed and quality to end-users.

This Object oriented programming test evaluates candidates’ ability to apply OOP principles to tackle problems concerning basic data types, variables, and control flow, objects and classes. It also covers candidates’ knowledge of four central principles of OOP: encapsulation, abstraction, inheritance, and polymorphism. Finally, this screening test also covers some more advanced OOP topics such as abstract classes and interfaces, exception classes, inner classes and generics.

The questions on this Object oriented programming test focus on different scenarios, creating applications useful in various fields. The questions are provided with examples of code in Java, but the core concepts are the same in all OOP-based languages, such as C++, C#, Python, PHP and Ruby.

Candidates who perform well on this test have an intermediate grasp of OOP concepts, and can find solutions for different problems surrounding the design of high-quality applications. This screening test will help you identify candidates who can build programs efficiently by applying OOP principles to their coding design.

David Felipe C.

VP of engineering, mid-market (51-1000 FTE)

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.

FAQs

An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.

A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now."

Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
