Identify and recruit candidates for developer roles using the Core Java Developer Assessment

The Online Java Assessment is a technical skill test hiring managers use to screen candidates effectively based on their proficiency in core Java concepts, such as OOPS, operators, interfaces and inheritance, and advanced topics, such as multithreaded programming, error and exception handling. It also includes a Java Online Coding Test to assess their basic programming skills.  

What is a Java Test?

The Java Test evaluates a candidate's knowledge and proficiency in Java. This pre-employment assessment objectively assesses a candidate's skills, knowledge, and conceptual understanding of Java before an interview.

Benefits of Java Test  

• Java is a coveted programming language used for desktop applications, embedded systems, enterprise-grade systems, and Android app development. The tech recruiters can gain precise and objective insights into candidates' capabilities and onboard diverse, talented individuals by conducting a Java Developer Test.

• These tests aid in reskilling and workforce planning initiatives to accommodate the changing industry needs. The insights generated from the Java Test reports help create a roadmap to address any potential skills gaps. In addition, when administered with psychometric tests, they can become a critical part of the holistic evaluation to uncover intriguing aspects of the candidate's personality and competencies.

What is inside this Core Java Developer Assessment?

Designed by seasoned subject matter experts, this Java Test includes carefully selected questions that test on-the-job skills. The test screens candidates for the specific abilities that recruiting managers look for in a Java developer with experience of 0-2 years. This 60-minute test comprises 18 multiple choice questions (MCQs) and one hands-on coding challenge to be conducted on a robust online coding simulator, Codelysis. Developed around Java best practices and standards, this Java Test enables employers to assess candidates on a range of skills essential for the success of a future hire.

What skills does this Java Test cover? 

A Java developer must possess the knowledge and skills in programming, software analysis, testing, and debugging, as well as the ability to make improvements to improve the existing processes, among other responsibilities. The skills include general Java programming, such as:

• Java basics: This section of the Online Java Test by Mercer | Mettl evaluates candidates' understanding of fundamental Java concepts, like strings, string methods, operators, interfaces, inheritance, flow of control, constants, variables, and data types.  
• OOPs: A candidate’s knowledge and understanding of object-oriented programming (OOP) principles are evaluated in this section. It covers OOP skills like cases, objects, collections, OOP concepts, interfaces, inheritance, etc.  
• Advanced topics: In this section, skills like threads, multithreaded programming, error resolution, exception handling, etc., are evaluated.  
• Hands-on programming: The Java Test by Mercer | Mettl also includes a section designed to evaluate candidates' coding skills using Mercer | Mettl’s coding simulator.

What roles can you assess for using the Core Java Developer Assessment?

This Online Java Test helps to screen candidates for the following roles:   

• Core Java developer- Core Java developers design, code, and test Java applications, troubleshoot and debug issues, and collaborate with cross-functional teams, ensuring the software's performance, scalability, and security. They are also responsible for maintaining code quality, documenting code changes, and staying updated with the latest Java technologies and best practices. 
• Junior Java developer- Junior Java developers assist in designing, developing, and testing Java applications, troubleshooting and resolving software defects, collaborating with senior developers to learn and improve coding skills, and following coding standards and best practices. They are also responsible for documenting code changes and participating in code reviews while being updated with Java technologies. 
• Java software developer- A Java software developer designs and develops Java-based software applications. Their responsibilities include writing clean and efficient code, resolving user-reported issues or providing technical support to ensure the smooth operation of Java applications. Java software developers must know security best practices and implement appropriate measures to protect the software and its data from potential vulnerabilities and threats.

Where in your recruitment process should you use the Java Online Coding Test?  

Competent employees are one of the cornerstones of any successful business. Therefore, finding and retaining top candidates has become crucial for any organization aiming for success in an increasingly competitive landscape. Moreover, recruitment is a time-consuming and expensive process requiring a well-structured strategy in which pre-employment assessments are pivotal.  

Hiring an extremely competent Java developer could be tricky, even for experienced recruiters striving to save time, effort, and resources. Java Developer Tests enable recruiters to streamline their talent assessment process efficiently. Therefore, they can find and hire coders who write clean, error-free codes to solve the problem.   

Hiring managers can save energy and resources when screening candidates from a vast pool of resumes with the help of the Java Online Pre-employment Test. From in-depth technical evaluation to objective insights into candidates’ employability skills, a Java Assessment covers it all, enabling recruiters to achieve their tech hiring goals efficiently and effectively. It is recommended that the Java Online Coding Test be incorporated after the initial CV screening and any initial assessments of candidates' theoretical knowledge of Java.  

The Java Test is a proven tool for understanding the candidate's conceptual and skill-based knowledge. This new-age tool takes precedence over traditional means of screening and provides insights to shortlist the top applicants for the next selection process step. This objective assessment focuses on the candidate's skills, knowledge, and competencies, making them a comprehensive evaluation tool for technical screening.

Sample questions for Java Coding Test  

• What are the benefits of using Java for software development?

Some benefits of using Java for software development include platform independence, object-oriented programming, robustness, and a large community of developers.   

• How does Java handle memory management?   

Java uses automatic memory management through garbage collection, which deallocates memory for objects no longer in use.   

• What is the purpose of a Java package?   

A Java package organizes classes and interfaces into a hierarchical structure, providing a way to manage and control access to the code.  

• What is the difference between a class and an object in Java?   

In Java, a class is a blueprint or template for creating objects, while an object is a class instance representing a specific entity or data.  

• How can Java be used for web development?  

Java can be used for web development through technologies like JavaServer Pages (JSP) and Java Servlets, which allow for dynamic web page generation and server-side processing.
