The Modern Java 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 covers a broad range of skill 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 Language Features such as records, sealed classes, pattern matching, and type inference with var. Candidates are assessed through a combination of Multiple Choice, Multiple Correct Answer, and Essay Composition questions, with some questions subject to individual time limits to discourage cheating and improve predictive accuracy. Questions are drawn from a large pool to further prevent cheating, and one or more questions incorporate artificial intelligence in the scoring process to ensure a thorough and fair evaluation of each candidate's practical Java programming skills.

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 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.
