About the Java (coding): Entry-Level Algorithms test

Java is a general-purpose language that is geared for distributed environments. It is one of the most popular programming languages for Android app development, embedded systems, desktop applications, and enterprise-grade systems.

Strong foundational knowledge of programming in Java is essential for junior programmers. Those candidates are able to hit the ground running and set themselves up for further professional growth.

This test gives candidates 10 minutes of time to complete a straightforward coding task. The code is evaluated against a set of test cases, some of which are available to the candidate to determine if they are on the right track.

This is a great initial screening test that allows you to effectively screen candidates based on essential skills.

We recommend combining coding tests with at least one of or cognitive ability tests evaluating numerical or analytical skills.

The test is made by a subject-matter expert

Crafted with expert knowledge

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.

What our customers are saying

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.

Review from G2

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.

Hire developers with a Java coding test

What is a Java online coding test?

The Java online test is a valuable tool utilized by hiring managers to assess candidates' proficiency in core Java concepts. This technical skill test enables a thorough evaluation of candidates' fundamental knowledge in areas like object-oriented programing, operators, interfaces, multithreaded programming, error handling, etc. By conducting the Java online test, hiring managers can effectively screen and evaluate candidates' Java skills, ensuring a more informed decision-making process in the hiring journey.

Java in business

Java is a high-level and general-purpose programming language used across many industries. This means the language is similar to human language, making it easier for a developer to understand and interpret, and as a general-purpose language, it can be used to build secure solutions for a variety of business needs. This contributes to Java being one of the most widely used development platforms and the preferred choice of developers across the board.

Its widespread use and open-source nature contribute to the large, supportive community that builds and shares Java application programming interfaces or APIs and other tools that make it easier to write code to accomplish complicated tasks. Some of the benefits of Java include:

• The Java programming language was created to be easy to use and because of this, it is also easy to learn, program, compile, and debug

• Programmers can use Java to build modular programs and reuse code because it's object-oriented

• Java is platform-independent, which means it can move easily from one computer system to another enables programmers to run the same program on many different systems

Java coding test benefits

How to hire a Java developer

Java’s multitude of applications make it a popular programming language in the software development world. This means that many candidates will be skilled in the language, but, as mentioned before, the demand for Java developers is also high.

So before deciding to hire a new Java developer, you need to define the skill set that fits your business needs. Assuming you already have an in-house development team, you probably know where the missing link is and where to add more resources. However, if you're setting up your team from scratch, formulating a recruitment plan and defining your business needs will help you recruit the essential skills and avoid costly hiring mistakes.

Hiring a developer means you’re looking for someone who will contribute to your business goals and play an essential part in the team. So when you hire, candidates must have both the skills and the personality attributes that will contribute to team strength and the organization’s culture.

Determine the skills you need

For any job, some hard skills are non-negotiable. This means the skills play a significant part in the success of the individual and the organization. Before you start recruiting, it is important to determine what these skills are.

Another consideration is soft skills. These play an equally important role in the recruitment process because soft skills such as communication and interpersonal skills will contribute to the success of the individual as well as their team. Soft skills help team members to build bonds and effectively collaborate to achieve goals, overcome obstacles and grow within their roles.

Pinning down which hard and soft skills you need for the role will help you to create a clear job description that will resonate with potential candidates.

Write a clear job description

Once you’ve established the skills required for the position, you need to describe it in a way that will appeal to potential applicants. Job descriptions communicate your company's requirements so that candidates with the right expertise can apply for those positions. They serve as a guiding light during the hiring process, and the most substantial reference for candidates to fall back on.

Share your job post on various platforms

With many businesses competing to get the best technical talent, only posting on your company's careers page may not be enough. The pool of people who see your job can increase significantly if you use social-media platforms, networking websites, and job boards. In addition, this can increase the chances of getting your job description in front of candidates with the technical skills for the position.

Hire with a Java coding test

Where in your recruitment process should you use the Java online coding test?

The Java online coding test is ideally used at a stage in your recruitment process where you want to assess candidates' practical coding skills and their ability to apply Java concepts in real-world scenarios. It is recommended to incorporate the Java online coding test after initial resume screening and any initial assessments of candidates' theoretical knowledge of Java.

Ultimately, the Java online coding test serves as a valuable assessment tool to validate candidates' Java coding skills and ensure their compatibility with the technical requirements of the position you are seeking to fill.

Add tests to your assessment

It is not enough to hire the most qualified candidate using a Java coding test. You also need to consider things like personality, culture, time management, and attention to detail when hiring.

Adding personality tests to your assessment can help you find the right fit for your team, based on the traits of your candidates. Other tests, like the culture-add test, can help you recruit a diverse workforce.

In summary

To streamline your recruitment process, TestGorilla’s pre-screening assessments help you evaluate candidates on hard and soft skills, and give you an unbiased view of individual skill competencies. Considering that it's nearly impossible to keep up with current developments and best practices in programming and software development, a Java coding test can help you identify the best candidate for the job.
