What to look for in Groovy developers

The Apache Groovy programming language is one of the oldest alternative programming languages running on JVM (Java Virtual Machine). It is dynamic in nature, with static typing and static compilation capabilities. The Groovy programming language is aimed at improving developer productivity thanks to a concise, familiar, and easy to learn syntax.

While screening a Groovy developer, it’s important to determine whether they have experience in developing applications, tools, and libraries in the Groovy language. Additionally, experience on larger projects, be it, web applications, distributed systems, tooling, or DSLs is a huge plus. Finally, understanding the candidate’s knowledge and application of Java will provide valuable insight into their suitability for the role.

Plutora is a value-stream management software. Before implementing DevSkiller, they used phone interviews to preselect their candidates. Those who passed through were invited to a technical interview followed by a behavioral interview. The lack of automation meant that a lot of manual work was required. Also, the effectiveness of phone screening was insufficient as it didn’t eliminate the candidates without the right skills. The solution? The successful implementation of DevSkiller into their technical recruitment process. Plutora’s aim was to automate their technical screening efforts, limit the number of interviews, and identify candidates with the right skills before the interview stage. 

The result?

“Thanks to automating the screening stage, we were able to reduce the interview rate by 50%. At the same time, the quality of candidates who make it to the interview stage is now much greater. DevSkiller adds an extra layer of quality to our technical hiring process”. 

Richard Williams – VP of engineering at Plutora

Frequently asked questions

What is RealLifeTestingTM?

The RealLifeTestingTM methodology forms the basis of all DevSkiller coding tests and interview questions. This methodology provides a holistic view of the candidate’s skill that would not be attainable from traditional methods like whiteboard testing or algorithmic puzzles. At its core, the RealLifeTestingTM methodology stems from the belief that the best way to evaluate a developer’s development skills is with a work sample test that mirrors the actual development work they’ll do. Our Groovy coding tests and interview questions require candidates to build full project apps or add features to existing apps, just like they’ll be doing after being hired. To do this they will need to show their knowledge of coding, in stack resources, resources like Stack Overflow to find solutions and decision making to find the best way to solve the problems they encounter. The results you see show the candidate’s coding skill, decision making, code cleanliness, and problem-solving skills.

How are Groovy online tests and interview questions evaluated?

Our platform gets to work as soon as the candidate finishes their test. The results are then automatically generated into a report that even non-technical recruiters/professionals can understand. Candidates are evaluated on whether the solution would run (an essential factor in all software development), whether there are any errors in the code, the quality of the code, and how it works in edge cases. We have a number of robust anti-plagiarism tools in place that ensure test accuracy by comparing results to every answer ever registered within the system. 

Do I need to be a programmer to use DevSkiller?

We made Devskiller as simple and as automated as it can possibly be. Our range of ready-to-use Groovy coding tests were prepared by Groovy specialists and allow non-technical users to verify the technical skills of their candidates. If you have a technical person on-site, you can prepare a custom test from scratch.

What’s the duration of Groovy coding tests?

Test duration is flexible and depends on your preferences. You have the option to use our default settings or set your own test duration. It is also possible to set time limits for individual questions within a test.
