R Coding Tests
When hiring R experts, you need to make sure their skills are up to scratch. Candidates proficient in R should be familiar with its data manipulation and visualization tools, as well as its statistical analysis and machine learning capabilities.
TestGorilla’s range of universal coding tests enable to you put candidates through their paces, helping you find top talent with the skills to support data-driven decision-making across your organization.
What is an R skills test?
R is an open-source programming language many programmers use in data analysis, data science, and machine learning. With proficiency in R, developers can create programs that enable businesses to visualize, analyze, and manipulate data.
Anyone can list R knowledge on their resume – but how can you ensure candidates really have the skills you need?
An R skills test is the best way to assess a candidate’s proficiency in this programming language. With TestGorilla’s expertly designed R coding tests, you can evaluate candidates for basic to advanced R skills and gain deep insights into their broader coding abilities.
Why use R skills tests?
Assess candidates’ technical skills in writing accurate R code – in situations relevant to their roles.
Ensure candidates are comfortable and perform at their best with a configurable IDE (integrated development environment) that lets them customize their workstations.
Gain an in-depth understanding of how candidates approach the task with a coding timeline that tracks events like pasting content or changing languages.
Reduce the risk of bias entering your hiring process and improve diversity when hiring for developer roles.
