About the Ruby (coding): data structures test

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 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.

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.
