This coding test assesses a candidate’s ability to program an algorithm in Scala, testing their programming skills. This test helps you identify developers with advanced Scala skills.
Scala developers, big data engineers, data engineers, backend developers, data scientists, machine learning engineers, and any other roles requiring an advanced knowledge of Scala.
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.

TestGorilla’s tests are created by subject matter experts. We assess potential subject-matter experts based on their knowledge, ability, and reputation. Before being published, each test is peer-reviewed by another expert, then calibrated using hundreds of test takers with relevant experience in the subject.
Our feedback mechanisms and unique algorithms allow our subject-matter experts to constantly improve their tests.
TestGorilla helps me to assess engineers rapidly. Creating assessments for different positions is easy due to pre-existing templates. You can create an assessment in less than 2 minutes. The interface is intuitive and it’s easy to visualize results per assessment.

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.

The Scala (Coding): Advanced Algorithms test will be included in a PDF report along with the other tests from your assessment. You can easily download and share this report with colleagues and candidates.
