Coding challenges test a candidate's ability to write Ruby code in real-time. These challenges often present a specific problem that the candidate needs to solve using Ruby. This type of assessment allows you to evaluate their coding style, logic, and overall understanding of the language.

2. Project-Based Assessments

Project-based assessments involve giving candidates a small project to complete using Ruby. This could include writing a simple web application or a script that performs certain tasks. This method assesses their practical skills in applying Ruby to real-world situations, as well as their ability to follow project requirements.

Using Alooba, you can easily set up and administer these assessments. Alooba's platform allows you to create customized coding challenges and project-based tests, providing you with the tools to accurately evaluate candidates' Ruby abilities. This streamlined process helps ensure you find the right Ruby expert for your team, boosting your chances of project success.
