The Modern Java (Short) assessment is designed to evaluate the knowledge and skills of entry-level to mid-level programmers in writing business applications using modern Java programming techniques and design patterns, with a primary focus on features available since Java 8. The test measures proficiency across key areas including Lambda Expressions and Functional Interfaces, Stream API and Collectors, Object-Oriented Design with Interfaces and Inheritance, Null Safety and Optional, Exception Handling and Resource Management, and Modern Java (Short) Language Features such as records, sealed classes, pattern matching, and the module system. Candidates are assessed on their ability to apply design patterns like Builder, Factory, Strategy, and Observer, as well as their understanding of concurrency, file I/O, and unit testing principles. The assessment measures skill-based competencies through a variety of question formats, including Multiple Choice, Multiple Correct Answer, and Essay Composition questions, with one or more questions scored using artificial intelligence. Questions are drawn from a large pool to minimize the risk of cheating, and one or more questions are subject to individual time limits to further deter dishonesty and enhance the predictive accuracy of results.

The specific attributes measured include:

Following completion, the test produces a Candidate Selection Report that includes an overall score and detailed scores for each attribute.

The Candidate Selection Report also provides expert interview questions that help you probe critical or low-scoring areas, along with a guide for noting your evaluation of the candidate's responses. Consistent use of an interview guide is an important part of gaining better candidate insights and making better hiring decisions.

Note that while the Modern Java (Short) assessment is a useful and efficient instrument for confirming a base level of skill or knowledge about this important topic, it is not intended to pinpoint the exact level of candidate or skill. We recommend that skills tests, like this one, be used in parallel with other measurements, such as cognitive ability, job fit, and behavioral history. Each different type of test provides a valuable piece of information you can use when evaluating potential job performance.
