The Object Oriented Programming Concepts test is designed to evaluate the knowledge and skills necessary for entry-level to mid-level programmers to design, develop, and maintain software using object-oriented principles. It measures proficiency across key areas including Classes and Objects, Encapsulation and Access Modifiers, Inheritance and Polymorphism, Abstraction and Interfaces, Object Relationships (Composition, Aggregation, and Association), and SOLID Principles and Code Maintainability. The assessment also covers design patterns, exception handling hierarchies, collections and generics, UML diagram interpretation, and object lifecycle management.

The test is delivered using Multiple Choice and Multiple Correct Answer questions drawn from a large question pool to minimize the risk of cheating, and one or more questions are individually timed to further discourage dishonest behavior and enhance the predictive accuracy of results. This format ensures a thorough and reliable measure of a candidate's or employee's real-world understanding of object-oriented programming concepts.

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 Object Oriented Programming Concepts 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.
