About the Scala (Coding): Advanced Algorithms test

Scala is a programming language designed to run on the Java Virtual Machine, allowing for full compatibility with Java libraries and frameworks. Scala is a powerful language with a concise syntax that offers many features and constructs, including functional programming and object-oriented programming paradigms.

A strong foundation in Scala is essential for success in a growing range of industries, from Big Data and Machine Learning to Finance. Candidates who are familiar with Scala's syntax and core programming concepts will be well-equipped to tackle more complex programming challenges.

This Scala test provides candidates with 60 minutes to complete a complex coding task that may involve knowledge of array manipulation, sorting, and understanding of algorithmic complexity. To do well on this test, developers must be familiar with efficient algorithms such as binary search or divide-and-conquer techniques, and have strong string manipulation skills, knowledge of algorithms, stack-based approaches, and an understanding of data structures such as sets or tries.

The developer's code is evaluated against a set of test cases, some of which are provided to the candidate to help them determine if they are on the right track.

This test is an excellent tool for screening candidates based on their applied knowledge of Scala programming. It can be used to effectively evaluate a candidate's skills and determine their potential for further professional growth.

We recommend combining coding tests with at least one of our cognitive ability tests evaluating numerical or analytical skills to gain a more comprehensive understanding of a candidate's abilities.

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.
