How our Java 8 interview questions work

The RealLifeTesting™ methodology is the driving force that makes DevSkiller Java 8 online tests and interview questions unique. The methodology works by putting the candidate in a real-world environment with specific problems that mirror the actual development work they’ll do. This helps assess potential candidates’ abilities better and provides a 360-degree view of a developer’s skills. This modern approach to testing eliminates previous ineffective algorithmic puzzles and games and provides results in a report that even a non-technical recruiter can understand. Our Java 8 online test will provide you with critical insight into your candidate’s coding skills, critical thinking, and time-management skills.

What to look for in Java developers when verifying Java 8 skills

Java 8 was a significant update to the Java programming language development that was initially released in 2014. Developers use Java for a wide range of applications. Although Java is one of the most widely used coding languages, it is constantly updated and changing and is not an easy-to-use language for non-programmers. This means an in-depth Java 8 test and assessment of candidates’ day-to-day skills is critical to understanding their abilities.

It is vital to verify the candidate’s knowledge and understanding of the different tools and libraries available. Without it, a programmer will waste time by writing everything from scratch.. Unless you are hiring for a junior or entry-level position, it’s vital to make sure the candidate has real-world experience, not just knowledge from university or a degree. Although Java has its own range of certificates, they do not offer much insight into the candidate’s current abilities. That’s why it is crucial to incorporate a Java 8 test alongside specific Java 8 interview questions.

Build your own custom Java 8 coding tests

Want to get more out of your Java 8 online test? No problem. With  Devskiller, you can customize your Java 8 test to any specific task or problem and build it out in any way that relates to your needs. With our intuitive and easy to use online platform, you can set the number of questions, duration, difficulty level, and the scope of each question while remotely monitoring the results in real-time.

Coding tests with built-in Java IDE!

To greater improve candidate experience during testing, Devskiller has now implemented a built-in Java IDE directly into the browser. That’s right, you read that correctly! Our already warmed up, ready to use Java IDE will reduce time during testing and increase the user experience for your candidates.

Candidates no longer have to clone their code, wait for the dependencies to install or indexes to build. They can literally start coding as soon as they open the test invitation. This unique feature will not only reduce candidate drop-off but will also reduce the time spent by candidates taking tours. This is just one of the many innovations that set DevSkiller TalentScore apart from the competition when it comes to developer screening.

Like the look of our Java 8 interview questions but need more?

Interested but still unsure if the Java 8 coding test will help your recruitment process? We understand how important these decisions are, and that’s why you don’t need to take our word for it but can hear from one of our many satisfied customers:


Aliz is a Big Data and Machine Learning specialized Google Partner that provides valuable insights and optimizes processes. Before switching to DevSkiller, their screening process consisted of take-home tests without a strict deadline that recruiters manually corrected. A technical interview followed this. The biggest obstacle they wanted to overcome was to lower the candidate dropout rate during screening. Once Aliz successfully implemented DevSkiller across three offices worldwide, they were able to have 25% fewer technical interviews while reducing the candidate dropout rate by 1.5x which resulted in one week saved on hiring time per candidate.

“With DevSkiller, we see a 50% increase in candidates staying in the pipeline at the screening stage. The automated correction of tasks is a game-changer for us.” – Vivian Szalai, Recruiter at Aliz.
