About the Swift (Coding): Working with Arrays test

Swift is a popular coding language for developing iOS, macOS, watchOS, and tvOS apps. Good Swift developers are highly sought after, and one of the skills required of them is working with arrays. Arrays are a fundamental data structure in Swift that allow developers to store and manipulate collections of related values efficiently.

This test assesses candidates’ skills in working with Swift arrays. It provides a task description in the appropriate context and specifies the algorithms that need to be developed and the requirements to satisfy. The test also includes a few examples to illustrate how the function should behave and asks candidates to solve the task. You can see a complete and functional example of a task by clicking the “preview question” tab on this page.

Candidates can run their code to see if certain pre-defined inputs return the expected result. The test is scored automatically using a different set of test cases, which include more challenging corner cases. Once the test is complete, you can inspect the code of the candidate and play it back to interpret their thought process. You can also see the efficiency of the code shown in the results.

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.
