Ruby has become one of the most popular languages for building web applications and is used on some of the biggest platforms and apps available such as the vacation booking site Airbnb, the streaming service Hulu, the popular developer site Github, and the review site Goodreads. Ruby boasts great flexibility, robust security, and short development periods, all of which have skyrocketed its popularity. Working with and implementing data structures is crucial to the success of a Ruby developer. An effective data structure enables developers to effectively manage, organize, and represent data. Data structures are often implemented as objects, so the ability to effectively work with objects and understand object-oriented programming is an equally important skill to have when dealing with Ruby. This Ruby coding test presents candidates with a data structure problem and gives them 30 minutes to implement a solution that meets the given requirements. Candidates can run the code against a few test cases to see if their solution is on track. Once they submit their test, the code is automatically scored by our software based on a more extensive set of test cases that also covers exceptions or corner cases. In the report you receive for each candidate, you can play back how the code came about in the coding editor.
