What is Java?
It is a speedy and scalable programming language. Based on WORA (write once, run anywhere), Java is both easy to learn and known for its stability. From its humble beginnings in 1995, Java has been successful because it’s object-oriented, general-purpose, and can be used across multiple platforms.
Because of its flexibility, Java is one of the most popular programming languages in the world. Without it, we wouldn’t have LinkedIn, UPS.com, and AliExpress, to name a few. Over 9 million developers use it, and many learn Java as their first programming language. With so many professionals familiar with Java, how do you find those perfect, expert Java candidates?
Criteria Used To Screen Java Developers
The criteria used to screen Java developers can vary from one organization to another, but here are some criteria that are often used:
- Technical skills: The developer should have a strong understanding of Java and its associated technologies and frameworks. This can be assessed through coding tests, technical interviews, and by reviewing the candidate’s past projects and experiences.
- Problem-solving skills: The ability to analyze problems and come up with efficient and effective solutions is crucial for any developer. This can be assessed through coding challenges and technical interviews.
- Experience: The number of years of experience the candidate has with Java and related technologies can be a good indicator of their proficiency. However, it’s important to also consider the quality and relevance of their experience.
- Certifications: Having certifications can be a plus, as they show a certain level of commitment and proficiency in the language.
- Soft skills: Communication, teamwork, and time management are also important skills for a developer. These can be assessed during the interview process and by speaking to references.
- Knowledge of best practices: The candidate should have a good understanding of best practices in Java development, such as coding standards, design patterns, and testing practices.
- Understanding of the full development lifecycle: The candidate should have experience with all phases of the development lifecycle, from requirements gathering to deployment and maintenance.
- Familiarity with tools and technologies: The candidate should be familiar with the tools and technologies commonly used in Java development, such as IDEs, build tools, version control systems, and testing frameworks.
Best Practices When Screening Java Developers
The interview process is one of the core elements when screening candidates for a Java development role. However, other processes, like job description creation and document acquisition, require careful planning to ensure everything runs smoothly once you get to the interview phase.
How do you write a Java developer job description?
When seeking a Java developer, it’s essential to create a job description that resonates with what skilled professionals are looking for while also encapsulating your organization’s specific requirements.
Here are various elements to consider when drafting a job description for Java programmers:
- Be specific: Instead of just “Java Developer,” consider specifying the role level or specialization, e.g., “Senior Java Developer” or “Java Backend Developer.”
Introduction to the company
- Company overview: Briefly describe your company, mission, and vision.
- Culture and values: Describe what makes your company unique. Is it a startup culture? Is it more traditional?

What documents should companies require when hiring a Java developer?
Not all companies need the same documents from their candidates, so analyzing which ones will be relevant for you is vital. These documents help validate the candidate’s qualifications and experience and ensure legal compliance.
Here are some options of documents to require when searching for a Java developer:
Resume or curriculum vitae (CV)
Provides a snapshot of the candidate’s educational background, work experience, skills, and achievements.
- What to look for: Relevant experience, skills, and qualifications that align with the job description.
Allows the candidate to elaborate on their experiences and interest in the role.
- What to look for: Personal motivation, understanding of the role, and how their experiences align with your company’s needs.
Certifications can validate a candidate’s expertise in specific areas, especially in the tech industry.
- What to look for: Java-specific or related certifications based on the job requirements.
Proof of academic qualifications.
- What to look for: Degrees, diplomas, or transcripts relevant to the field, such as Computer Science or Software Engineering degrees.
Professional portfolio or work samples
Demonstrates the candidate’s actual work, showcasing their expertise.
- What to look for: Code samples, GitHub repositories, or case studies relevant to the role.
Contact details of past employers or colleagues who can vouch for the candidate’s skills and work ethic.
- What to look for: Feedback on the candidate’s technical prowess, teamwork, problem-solving abilities, and general work demeanor.
Validates the identity and legal work status of the candidate.
- What to look for: Government-issued ID, passport, or work visa (for international candidates).
If your company decides not to require certifications or degrees, that’s valid! Real-world skill is not always measured in coursework, and some of the best programmers may be too busy working to get a certification.
What tests should Java developers complete in a recruitment process?
Hiring a Java Developer requires more than just vetting resumes and conducting interviews. Testing plays a pivotal role in identifying candidates who not only have the theoretical knowledge but also the practical skills to excel in real-world situations.
Here are some vital tests when looking for a Java developer:
Technical coding tests
- Purpose: To evaluate the coding prowess and problem-solving capabilities of the candidate.
- Algorithm challenges: Questions that require candidates to craft efficient solutions to programming problems.
- Debugging tests: Presenting candidates with faulty code and asking them to identify and rectify errors.
- System design: Testing their knowledge of designing scalable and efficient systems.
Framework and library assessments
- Purpose: To gauge the candidate’s expertise with specific Java frameworks and libraries.
- Hands-on tasks: Providing a mini-project or task to assess their expertise in a specific framework.
- MCQs: Multiple-choice questions about particular functionalities or best practices related to the framework.
Soft skills assessment
- Purpose: Evaluate interpersonal and communication skills.
- Situational judgment tests: Presenting candidates with hypothetical, job-related situations to assess their problem-solving and decision-making skills.
- Group discussions: Observing candidates in a group setting to evaluate their teamwork, leadership, and communication skills.
Since every project and company is different, there is no one-size-fits-all skills test.
Many platforms, sites, and software are created to test Java developers’ skills. Some are customizable and can even use your code base. However, if your company is looking for a custom assessment, WillDom can help you design one that fits perfectly with your company’s needs.
