O que procurar em um desenvolvedor Java

Java is a compiled, object-oriented programming language. It is intended to let application developers “write once, run anywhere,” meaning that compiled Java code can run on all platforms that support Java, without the need for recompilation. However Java is not considered the easiest programming language to use for non-programmers, so you will want to hire the right Java developer for the job. 

It is important to understand that the Java world evolves quickly so your ideal candidate will need to have up to date, relevant experience. Your Java developer will need to have an understanding of Java language through collections, “streams” and lambda expressions and concurrency through thread pools. They should have knowledge of frameworks including Spring Boot 2, Hibernate and SQL, JUnit, and Spock among others. As well as the language itself, your Java developer will also need to have knowledge of the tools and libraries of the language, such as Maven and Gradle, Git, and Docker – this will pay dividends in time-saving further down the line. Finally, your Java Developer should have hands-on, practical experience of working on actual coding projects, be it commercial or otherwise.

Ada Health 

Ada Health is a global health company founded by doctors, scientists, and industry pioneers to create new possibilities for personal health. The company previously screened tech skills through an on-site task, followed by a team interview- a procedure that required a great deal of time. For this reason, the biggest objective Ada had was an improved interview experience that would save time. 

“DevSkiller helped us to save precious on-site time for applicants that are already likely to be a fit. We’re saving 3 hours per candidate – that was the time we spent with applicants on a technical task before.” 

Micha Gerwig– Engineering Manager Ada Health 

Perguntas mais frequentes

How are Java online tests evaluated?

With our Java online tests, once the candidate has completed the test, the results are automatically evaluated and presented in a clear and concise way. You don’t have to be technically minded to understand them. Each candidate is evaluated based on the solutions they have provided, with each candidate being assessed based on whether their solution would work, the quality of the code, and any errors in the code. In addition, extra features test for plagiarism from previous tests.

Como é que os candidatos fazem um teste?

DevSkiller’s Java online tests are accessible from anywhere, meaning all the recruiter has to do is provide the test, then it is up to the candidate to come up with the right results. Each test can be made accessible for a limited time. Candidates can complete tests using their favorite IDE and then clone the project to GIT. Candidates can also run unit tests to make sure their solutions are effective. Once completed, test results are automatically evaluated and presented to the recruiter in the form of a report. 

How long does it take to set up DevSkiller?

DevSkiller provides an extensive library of Java coding tests, meaning you can start testing candidates immediately after setting up your account. The whole process of setting up your Java coding questions can take as little as five minutes. 

What do candidates think of DevSkiller tests?

Feedback received from candidates is that they love the structure of DevSkiller Java coding tests. We find candidates like having a chance to prove their software development skills, rather than simply trying to churn out old algorithms that they haven’t touched since they were students. They also like that DevSkiller tests use normal coding practices and conventional tools like unit testing and cloning to GIT from a personal IDE. 

If developer candidates are apprehensive about taking the test, their suspicions usually come from experience taking algorithmic tests- tests that don’t monitor the actual skills a developer uses on an everyday basis. With DevSkiller online tests, we find that candidates can immediately tell the difference and can test their Java coding skills in a way that is challenging but also a fair representation of the type of work they will be doing. 

What’s the test duration?

Java coding tests are flexible and you can set the duration to suit your own preferences. You have the option to use the default settings, or to cater the test to your own needs. Furthermore, each individual question within a test, can also be set with time-limits.
