Java (coding): entry-level algorithms

Online Java test: Pre-employment coding assessment to hire the best entry-level developers

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.

Hire developers with a Java coding test

How a Java coding test can help you hire the best

The tech recruitment field remains competitive, and with that, Java developers are still in demand. Between establishing whether they have sufficient skills to contribute to your company and finding a hire who will thrive in the role, recruiting can be challenging.

One surefire way to ensure your candidates have the right skills is by using Java code tests. Pre-employment testing can simplify your hiring process and highlight which candidates are best for the role. But before we look at how to hire, let's see what Java is and how it’s used in business.

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

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.

Recruit with Java code tests

Bad hires are extremely costly and can result from a failure to accurately assess a candidate's skills. This can happen because you're using inappropriate tools, don't have enough data, or don't analyze the data effectively.

For the initial screening stage, nothing works better than skills tests. Tests can range from basic skills to more elaborate projects and even job simulations. When recruiting candidates with an online Java coding test, you can gain insight into your candidates’ skills and proficiencies while making data-driven, unbiased hiring decisions.

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.


What is the difference between an assessment and a test?
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.
Can I add my own questions to an assessment?
Yes! Custom questions are great for testing candidates in your own unique way. We support the following question types: video, multiple-choice, coding, file upload, and essay. Besides adding your own custom questions, you can also create your own tests.
How do video questions work?
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." You can learn more about video questions here.
Can you explain how the other custom question types work?
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.
Can I customize an assessment with my company logo and color theme?
Yes! You can add your own logo and company color theme to your assessments. This is a great way to leave a positive and lasting brand impression on your candidates.
