About the Ruby (Coding): Debugging test

One of the most popular languages for building web applications, Ruby has been used to build 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's great flexibility, robust security, and short development periods have skyrocketed its popularity with developers and companies that want great results fast.

The ability to understand and debug code is a critical skill for successful Ruby developers with advanced coding knowledge. As new features are being developed, bugs may be introduced into the code and disrupt the regular function of your software. It is, therefore, important for a developer to be able to identify bugs in the code based on a set of requirements and fix them. Given the collaborative nature of software development, it is also critical to be able to work with and correct the code of other developers.

This test provides candidates with a small script that contains one or more bugs. The description clarifies the objective of the code and provides examples to illustrate how it should function. Candidates must then identify the bugs and fix them.

Candidates can run their code to see if certain pre-defined inputs return the expected result. Once candidates submit their code, the test is scored automatically using a wider set of test cases, which include more challenging corner cases. You can then inspect the code of candidates from your dashboard and play it back to see their thought process and how they came to their solution.

VP of engineering, mid-market (51-1000 FTE)

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.

FAQs

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.

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."

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.
