Hire A Java Developer- Skills He/She Should Have

Java is one of those languages which is in demand and will stay in demand. However, this demand is disrupting the market because everyone is claiming to be a perfect Java developer. Whenever you are looking to hire a Java developer online, it is vital that the candidate should demonstrate hard and soft skills.

Hard Skills A Candidate Should Have

When you hire Java developers, the candidate must be able to deliver medium and large tasks and show strong coding skills. The candidate should be able to write clean and optimized code, along with the knowledge of troubleshooting the code in case of bugs. The code candidate has written should be easily migrated to other frameworks and software. 

If you want to hire a dedicated Java developer, he should be comprised of the following tech skills

• Software design ( Object Oriented Programming, Solid, Kiss, Microservices, CQRS, SOA)
• NoSQL or Relational databases ( PostgreSQL, MongoDB)
• Knowledge of Java ( JPA, Lambda, Java 8+, Streams API)
• Testing ( JUnit, TestNG, etc.)
• Web Dev ( CSS/HTML, HTTP API design, etc)
• CI/CD Tools ( Maven, Gitlab CI/CD, Jenkins, Gradle)
• Containers ( Dockers, Compose, etc.)
• Cloud Services ( AWS, Azure, Google Cloud)

Soft Skills A Candidate Should Have

One of the first soft skills when you hire a Java programmer online should have teamwork capability. Coding is all about playing in teams. So, it is crucial that a candidate should be communicative and can give his/her own input and suggestions. 

Secondly, time management is a skill that should be present in the candidate when you are looking to hire a Java developer. The candidate should be able to deliver the tasks and project in time so that the team can complete the project in a timely manner.

Interview Questions that You Should Ask When You Hire Java Developers

In our world, people think that if they have theoretical knowledge, they also possess practical knowledge. See, theory without practice is nothing. If you want to be a skilled Java developer, you have to practice. Similarly, practice without theoretical knowledge is also nothing. You cannot code without having the knowledge of how to code. 

But how can you judge whether a candidate is strong on the practical side or theoretical side of Java? Well, that can be done by asking questions during the interview. However, there is a catch to this. It is not about seeing whether a candidate is capable or not, so there is no need to ask difficult questions. Keep the flow of conversation casual, only touching the tip of every question.

Here is what you can ask from the candidate.

• Topics related to Java core
• Questions about Databases
• Questions of Multithreading
• Tools and libraries questions
• About APIs and integrations

Hire Java Developers-How to do that?

Now that you have the knowledge of what Java is and what type of skills a candidate should have, let’s talk through the steps when you want to hire a dedicated Java developer. 

Choose the type of Java developer

The first thing that you need to do is decide what type of Java developer for hire you want. You can find even more details on hiring these professionals in this article. Whether you want to outsource the project or looking for a full-time developer. Or, do you want a part-time remote developer? Here are the platforms from which you can choose from:

• Freelance websites (Upwork, Fiverr)
• Recruiting Agencies
• Offshoring companies

Go through the Portfolio

Once you have decided what type of Java developer you want, it is time to check the portfolio. See whether the candidates you have selected meet the hard/soft skills of your project and what type of experience they have. If the developer is offshoring freelancers, look at the reviews of their past clients and see what they are saying. 

Screening and Interview

After filtering out the potential candidates, set up an interview and screen the candidates. When you hire Java developers, ask them the interview questions (mentioned above) and see whether they are capable or not. 

Hire A dedicated Java developer

If everything goes smoothly, it is time to hire a Java developer from that candidate list. Make sure to set up proper contracts and non-compete agreements. Moreover, introduce the Java developer to your existing team so that he can understand the workflow.
