Evaluating Java Coders for Hire

Evaluating Java Coders for Hire

Almost every application today is at least partly run on Java programming language. Google, Netflix, and Uber, among other companies with a worldwide reputation, use it in their products. But if you decide to create an app for your business needs using Java, the problem of testing and evaluating potential development team members arise. In this post, we will talk about the basics of this process, which can help even an absolute beginner without a tech background. 

Why Choose Java For Your Project

The biggest advantage of Java is its ability to run on any hardware and OS thanks to JVM (Java Virtual Machine). Basically, it is possible because any code written in this programming language opens and runs with help of JVM. This makes the development process for multiplatform apps much easier and more cost-effective. Other advantages of this language include increased data security, object-oriented nature that helps to reuse code, simple syntax easy to learn and understand, and support of multithreading. 

There are already 19 versions of Java and they keep coming. The professional community of coders around it is enormous and has proven to be really active. According to a survey held in 2019, there were around 9 million Java developers in the world, and this number only grew since. So, naturally, you will probably want to create an app with the help of this highly popular language. 

Hard Skills To Look For

Because of Java’s platform-independent nature, the number of tech products you can develop with its help is really enormous. The list of skills necessary for every team role will vary depending on your app category. You can categorize it with help of numerous online guides, you just need to have a clear blueprint for the future application on your hands with a list of basic features and preferably design requirements. 

No matter the team role, project category, and level of experience, every Java developer needs to have a basic understanding of language basics (such as variables, classes, data types, and exceptions), principles of JVM work, familiarity with most popular frameworks, Spring and Collections, for example. A list of questions for initial vetting can easily be found online, even if you don’t have any clue about Java basics. 

After the initial screening, you will need to become more specific. If you worked on job descriptions thoroughly, the number of unqualified candidates who will reach out should be really low, but still, you need to be prepared. The list of hard skills required for every team role and type of developer is really lengthy and can be found online, but unless you have an extensive tech background or are willing to invest a ton of your time in research, it can be a headache to test candidates’ by yourself. Those lists include potential team members’ knowledge of Java build and testing tools, EE components, AI learning technologies, web technologies, DevOps tools, and many other things that can leave even IT professionals somewhat confused. It is best to have an experienced tech lead, a senior developer with at least 3 years of experience, who will help you with the interviewing and vetting process. 

You can go further than simple questions and test candidates’ practical skills. There are a lot of coding tests for Java developers online, don’t be shy and ask your potential employees to spend 20 minutes of their time. Another great option for evaluating software engineers’ skills is searching for their presence in online professional communities. There is a great probability that they shared some samples of code or examples of previous work there with other coders. 

If you decide to seek help from recruitment professionals or outsourcing vendors, vetting candidates will no longer be your problem. Before you are presented with developers’ resumes, they are already tested by experts and went through basic background checks. But while hiring through staffing agencies or outsourcing Java software engineer, you will have to pay close attention to soft skills.

Soft Skills

Soft skills are often overlooked by tech professionals, but you as a business owner will need to pay close attention to it. To ensure hiring developers who will be a perfect fit for your team and corporate culture, you will need to actively participate in the interviewing process, even if staffing or outsourcing agencies usually handle this kind of stuff on their own. 

First of all, you will need to pay attention to the candidate’s communication skills and the ability for teamwork. With the development process being a team effort, they will need to actively work with other coders, designers, testers, and other IT professionals. If you are hiring from abroad, you will need to learn about candidates’ local culture and find out if they will be able to be integrated into your team. If you are building a remote team, ask about developers’ ability for self-discipline and organizational skills. 

Generally, Java developers need to have great attention to detail to ensure high-quality code, outstanding abilities for problem-solving and time management, great work ethic, and adaptability. Because of Java’s dynamic nature and constant updates, candidates will need to prove their ability to always learn about new language’s features and supporting tools and technologies. If just one member of the development team possesses some outdated knowledge, the whole process can be held back. 

Final Thoughts

The pool of talent for Java developers grew significantly in the last few years. It can seem easy to hire experts in this programming language because of this, but it can be deceiving. Because of the big number of inexperienced workforce, you will need to work twice as hard to ensure the hiring of really skilled software engineers. With a clear vision of the future project, a list of technical requirements, and the app’s category determined, the whole process should be much easier. With the help of online questionnaires or a skilled tech lead, you will be able to give potential developers’ skills the right evaluation and build a successful product for your business needs.
