About the R (Coding): Intermediate Level Algorithms test

R is a popular programming language for statistical analysis, data visualization, and machine learning. R is fast, flexible, and has an extensive range of packages and libraries, making it a go-to choice for data science projects.

This coding test assesses candidates' ability to create code in R that satisfies specific requirements stated in a task. Candidates are provided with an online coding editor in which they add their own code. They can run their code to test if the result matches the expected output of a set of pre-defined test cases.

The test covers intermediate-level concepts of programming using R and is geared towards developers with some experience in R.

Once candidates submit their answers, the test score is calculated by running the code against a set of test cases that are not available to candidates. These test cases are more comprehensive than what candidates see during the test. The score represents the percentage of test cases that are passed correctly. In your assessment dashboard, you can inspect the code of each candidate and play it back to see how the candidate produced it.

We recommend combining coding tests with at least one of our cognitive ability tests evaluating numerical or analytical skills.

The test is made by a subject-matter expert

Gary R

Gary has been working in the data science field for more than three years and is proficient in the fields of machine learning and data analysis. He has a Bachelor’s degree in Economics and a Master’s degree in Computer Science. The combination of those two fields helps Gary to achieve even greater results. He is fond of computer science and loves to work on projects related to Artificial Intelligence which is, in his opinion, the future of our world.

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.

We used TestGorilla to hire external developers.

Overall very good, we found the right developers who we hired for certain projects. It made it much easier and for sure quicker when you have many candidates who are applying for one job ad.

Easy to use and ability to choose the right tests from a wide variety. With the ability to invite candidates in just a few clicks. Once the candidates invited, it was super easy to track in which part of the process each individual was. Not to forget to mention, the software makes it possible to request a video presentation from the candidates to fulfill where I could ask for a question or topic they can present themselves.

Great platform! It is developer/coding specific and that is exactly what we needed and were looking for! I also love that it has a lot of culture questions!! This is something we like to focus on in our interviews.

FAQs

What is the difference between an assessment and a test?

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.

Can I add my own questions to an assessment?

Yes! Custom questions are great for testing candidates in your own unique way. We support the following question types: video, multiple-choice, coding, file upload, and essay. Besides adding your own custom questions, you can also create your own tests.

How do video questions work?

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." You can learn more about video questions here.

Can you explain how the other custom question types work?

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.

Can I customize an assessment with my company logo and color theme?

Yes! You can add your own logo and company color theme to your assessments. This is a great way to leave a positive and lasting brand impression on your candidates.

What type of support do you offer?

Our team is always here to help. After you sign up, we’ll reach out to guide you through the first steps of setting up your TestGorilla account. If you have any further questions, you can contact our support team via email, chat or call. We also offer detailed guides in our extensive Help & Inspiration Center.
