How our Online Java skill tests work

Using the RealLifeTesting™ methodology, DevSkiller’s Java programming interview questions help put your candidate in an environment to examine their coding skills. Give them access to all the tools they need to complete a range of tasks that they’d face regularly as a developer in your company.

Create deadlines and build a range of scenarios and tasks to help measure and asses your candidates’ problem-solving and technical thinking

Vigtigste funktioner

  • Asses candidates’ Java development skills in an environment you’ve designed and measure their coding abilities, rather than academic credentials
  • Test Java developers anywhere in the world at any time of day with Java skill tests
  • Et naturligt kodningsmiljø, hvor din kandidat har adgang til alle de værktøjer, der er til rådighed i det job, du ansætter til
  • Opret automatisk en rapport, der er let at læse og forstå for ikke-tekniske rekrutteringsfolk
  • Verify the integrity of your candidate’s work with robust and complex plagiarism controls

Hvad du skal kigge efter hos en Java-udvikler

Java is one of the most widely used coding languages out there. With such a versatile language, it’s important you know as much as you can about your Java developer. A Java developer that understands the tools of the trade, more than the language itself is a highly sought-after skill. This is because languages and frameworks are always changing, and what was being used only 5 years ago is obsolete by today’s standards

Java has its own range of certificates, but these are hardly reliable as they do little to assure a recruiter about a Java developer’s capabilities. That’s why it’s important that, alongside a traditional interview, you use an online Java skill test to check the skills that are specific to the position you’re recruiting for.

Find Java interview questions

Looking to find Java interview questions? DevSkiller Java tests include a wide variety of questions that are suited to any Java developer position. The Java programming language is constantly changing, which means having a wide range of current Java interview questions is vital to provide a complete understanding of the candidate’s abilities. It can be hard trying to find the best core Java interview questions that are suited to the specific role you need. That’s why each DevSkiller account comes with Java tests preloaded with real-world questions that can also be customized to suit the current position. This includes Java interview questions for experienced professionals.

Get ready for Java assessment test

As the Java environment is constantly changing, it’s even more important to get ready for a Java assessment test. This means making sure you understand the entire Java environment from its frameworks and tools to the Java language. DevSkiller tests speed up and smooth out this process by providing companies an infrastructure that lets them use their own codebase or our ready-to-use Java coding tests. When you get ready for the Java assessment test, it is important to remember that a developer may have a university degree, but this isn’t necessarily useful when it comes to business coding. Unless you recruit for an entry-level or junior position, the candidate needs to have recent real-life experiences such as commercial, hobby, or open-source programming.

You won’t need to worry when getting ready for a Java assessment test, as we include the most important core Java interview questions for junior positions to Java interview questions for experienced professionals.

Example Java programming interview questions

Finding the right example Java programming interview questions can be tiresome. The RealLifeTestingTM methodology is the foundation for all DevSkiller Java tests. It provides real-world situations for candidates so you can test the skills that a developer will use in their day-to-day work. This helps to provide a better understanding of the candidates’ abilities. Candidates also prefer this form of testing over typical example Java programming interview questions. It allows them to understand the position better and perform at their best. This method also offers Core Java interview questions as well as Java interview questions for experienced professionals.

Kan du ikke se det, du ønsker?

Can’t find the online Java coding test you’re after? No worries. Use DevSkiller’s Task Wizard to create your very own coding test and give your candidate access to everything they need. Create a task that focuses on problems common in your business, test the right skills, and make the best hire.

Built-in Java IDE

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

Kandidaterne behøver ikke længere at klone koden, vente på at afhængighederne installeres eller indeksene bygges. De kan bogstaveligt talt begynde at kode, så snart de åbner testinvitationen. Denne unikke funktion er blot en af de innovationer, der adskiller DevSkiller TalentScore fra konkurrenterne, når det gælder screening af udviklere.

Want to be sure that our Java programming interview questions and Java programming tests really work?

Knowing where to invest your business’s money is a big decision and not one that should be taken lightly. At DevSkiller, we’re sure that our Java programming interview questions are exactly what your company needs, but we’ll let some of our past customers do the talking instead:

Magdalena Rogóż - Vice marketingchef hos Kodilla

"Det er to gange mere omkostningseffektivt at bruge DevSkiller til at bedømme testene, samtidig med at vi giver vores studerende en meget bedre test og forbereder dem på fremtidige rekrutteringstests."

Ivana Nikolic - HR Manager hos ImpacTech

"Den største fordel for kandidaterne er, at de kan gennemføre prøverne, når det passer dem bedst. Hvis du har en kandidat, der allerede er i arbejde og overvejer at skifte karriere eller flytte til en anden virksomhed, er det også en tidsbesparelse for dem, da de ikke behøver at tage fri for at deltage i mange samtaler i jagten på en ny stilling."

Victoria Cyczewska - Specialist i talentindkøb hos Stepstone Services

"Vi har nu et værktøj, som ikke kun gør det muligt for os at samarbejde om at lave tests til vurdering af de tekniske færdigheder, som vi har brug for at udvikle, men også at kommunikere internt og eksternt (med kandidater). Desuden er vores tekniske rekrutteringsproces nu mere struktureret. Som et eksempel bruger vi vores tekniske screeningsresultater som en samtalestarter under tekniske samtaler."

Ofte stillede spørgsmål

Hvad er RealLifeTestingTM?

The RealLifeTestingTM methodology is the foundation of all DevSkiller Java programming interview questions. RealLifeTestingTM differs from traditional coding tests and algorithm puzzles, by providing recruiters with a complete view of a developer’s skills. It’s based on the idea that the best way to challenge a Java developer is to provide them with work similar to that which they will do within their role. RealLifeTestingTM simulates the actual work environment of a Java developer and sets them tasks based on this simulation.

To be successful, developers need to demonstrate their knowledge of coding, be able to use resources like Stack Overflow and find solutions to the problems they encounter. The best candidates are those who can demonstrate their coding skills, decision making, code cleanliness, and problem-solving.

How long does it take to set up TalentScore Java programming interview questions and Java programming tests?

DevSkiller Java programming interview questions are very quick and easy to set up. Our IT experts have created a testing model that is designed to be efficient and easy to use- whether you’re a developer yourself or not. The DevSkiller platform comes packed full of ready-made Java programming interview questions, so all you need to do is set up an account and start sending out test invites.

Skal jeg være programmør for at bruge DevSkiller?

Part of the aim of DevSkiller’s screening tool is that you don’t need to be an expert developer to be able to get the most out of it. Recruiting managers who have little, or no experience in software development can see for themselves how effective and time-saving our Java programming interview questions are. DevSkiller testing is as user-friendly as possible. Our test results are generated automatically and results are presented in a way that is easy to understand, even for non-technical recruiters. If you have someone technical available you can custom build your own tests and set your own specifications, or our default tests come ready to send.

Hvad er testens varighed?

It’s important that you have as much control over your own recruitment process as possible. Therefore the duration of our tests is flexible and will depend on your needs. Each test comes with default settings, which can be altered if required. You can even set time limits for individual questions within a test if you need to.
