Java Online Assessment Test

Object-Oriented Programming is a programming style that is associated with the concepts like class, object, Inheritance, Encapsulation, Abstraction, Polymorphism. Most popular programming languages like Java, C++, C#, Ruby, etc. follow an object-oriented programming paradigm. In OOP, computer programs are designed in such a way that everything is an object that interacts with other objects. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.

The test is designed to enable recruiters and hiring managers to quickly identify which candidates should be invited to an interview.

This test will assess candidates on their fundamentals and depth of Java programming languages with questions on:

• OOPs basics
• Strings
• Classes
• Interfaces
• Multi-threading
• Design patterns
• Exception handling etc.

The questions are designed to test for on-the-job Java skills as opposed to just theoretical concepts. The programming and debugging challenges test the problem-solving and coding ability of your candidates.

Depending on the role and industry, a Java developer might require these skills:

• Understanding of Object-Oriented Programming concepts
• Understanding of when to use design patterns such as Singleton, Factory, Fly-weight, Builder, Object Pool, Iterator, Strategy, Visitor, Composite. This skill is particularly important for senior Java developers who will have to work on the architecture of applications to design long-term solutions
• Understanding of the class loading process and how class loaders work
• Deep understanding of the nuanced world of performance, whether that be memory overhead, computation complexity, or speed
• Knowledge of when memory is being allocated, from what context, and how it affects heap fragmentation
• Familiarity with the various garbage collection algorithms, and how to use the profilers
• Experience with JSP / Servlets, Web Frameworks like Struts / Spring, and Service-Oriented Architecture / Web Services – SOAP / REST
• Ability to apply the most modern patterns and language features to existing systems
• Experience in using technologies in the Java ecosystem: Struts, Spring, Maven, Gradle, Ant, JUnit, Spock, and Hibernate, among many others
• Knowledge of the intricacies of SQL queries
• Ability to learn new technologies and willingness to step out of comfort zone to explore and learn new skills

Every role is different and requires a custom assessment to identify top candidates efficiently. Adaface subject matter experts understand your job description/ role requirements and pick the most relevant questions from our library of 10000+ questions to create a technical assessment that helps you find the qualified candidates in your candidate pipeline quickly. All custom assessments are set up based on the job description, role requirements, must-have skills, experience level and salary range within a maximum of 48 hours and you will get an email notification once it goes live.

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.

We believe that status quo tech assessment platforms are not a fair way for companies to evaluate engineers because they focus on trick questions/ puzzles/ niche algorithms. We started Adaface to help companies find great engineers by assessing on-the-job skills required for a role. Read more about why we started Adaface.

Here's what's different with Adaface:

• High quality non-googleable questions that test for on-the-job skills as opposed to theoretical knowledge.
• A friendly conversational assessment with a chatbot, instead of sending a "test" to a candidate. This translates to a higher completion rate. Adaface assessments (86% candidate completion rate), as opposed to traditional tests (40-50% candidate completion rate)
• Customized assessments for 700+ skills at different experience levels.

We have the following anti-cheating features in place:

• Web proctoring
• Webcam proctoring
• Plagairism detection
• Non-googleable questions
• Secure browser

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. As in an assessment is optimizing to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 60%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

You can check out our pricing plans.

The platform is completely self-serve, so here's one way to proceed:

• You can sign up for free to get a feel for how it works.
• The free trial includes one sample assessment (Java/ JavaScript) that you will find in your dashboard when you sign up. You can use it to review the quality of questions, and the candidate experience of a conversational test on Adaface.
• To review the quality of questions, you can also review our public questions for 50+ skills here.
• Once you're convinced that you want to try it out with real assessments and candidates, you can pick a plan according to your requirements.
