  526

The current times are marked by Digital transformation. Hiring not so right Java developer will have lasting repercussions for your business. This is a critical decision as Java has evolved and it is because of the continuous advancements that the adoption of the programming language has also risen. There is no dearth of talent in the marketplace especially in the world of software but to boil down to the perfect match for your business.

Here is a list of things you should be considering:

1). Java Skill set:

Java Developers have a special place in the landscape of software development, so before you start hiring you have to be sure of the skills which are essential to your business. As an unsaid rule, every new team member, in particular, a Java Developer should be able to contribute to the performance of your business. However, if you have any specific framework of Java-like Groovy on your mind, you have to make it clear to the candidate. In case you already have a proper development team in place, then you already know about what is missing to complete the deal. You also know what kind of resources will fill the gap for you. In case if your requirements are based on the niche development skills, then you have to look for the efficiency in coding. However, if you are building your team, then you need to have a concrete plan in place. In the personal interview, you will have to look for their knowledge of basic Java concepts and other skills as how they will triage a bug with an application, etc.

2). Problem-Solving Skills in Java:

It is essential for every Java Developer to be able to create, administer and manage the code with ease. This should also involve solving any problems which are encountered during the stage of testing. This can be checked by way of a live technical test as it will be a great platform for them to showcase any previous knowledge of working with design patterns, enterprise applications, multi-threading techniques, HTML, CSS, etc. It is also advisable to undertake the STAR (Situation, Task, Action, Result) interview strategy which involves putting behavioral questions wherein the candidate has to offer real-time examples and scenarios where they have personally used Java for fixing the development issues.

3). Knowledge of Frameworks Java:

One of the core parts of your process of planning is to decide on a particular Java Framework which is best suited to your development requirements. Thus, any developer which you finalize should bring in to the floor all the previous and relevant experience in the same line. In software development, every framework which is utilized will let you create different elements which have to be brought together later to fit the needs of your business. The Java landscape is replete with frameworks which are suited to the language and have no compatibility issues. Thus, if you are diving in a specific route, you will have to look for a developer who can match the specs and can deliver the product within the assigned time-frame. Thus, before the interview, it is a must that you become familiar with the chosen framework. You should not only ask for previous work experience on the framework but also look for their zeal to keep abreast with the latest updates and trends in the same.

4). Flexibility in Approach:

When you hire a developer, you should have a bigger picture in view. You need to have a futuristic view, e.g. if you hire a developer who has an expertise in one Java version but going forward when you will expand, the same version may not fit your needs so you should be able to make a prudent choice now. Thus, you should invest time and resources to search in both the contract and permanent market for the right developer who has mastered a particular skill and is open to upskilling and can build on their theoretical knowledge. The developer which you ultimately hire should be able to adapt to the changing requirements of the spectrum which is constantly evolving. Thus, hiring a person with a flexible approach is always a beneficial investment. You should make sure that the candidate can handle the release cycle as a whole.

5). Specialized Knowledge Java:

There are many pillars of Java development. So, before you start the interview process, you should be aware of the basic cornerstones of the Java landscape and decide on the one which is needed for your concern. This will also define your budget as developers who have expertise in some particular areas have higher salary demands. Thus, any developer which you will ultimately hire should be versed with the following basics.

a). Core Skills

  • Knowledge of string and string method: During the development, your business will be storing its data in different variables, and thus your developer has to be familiar with the string class and other objects for easy categorization.
  • The clear meaning of a Class and Object as each class in Java has a particular method which gives the string length.

b). Arrays and vectors

  • The developer should have clear knowledge that an array has a specific size which has to be defined before while a vector can grow or shrink according to the content.

c) Control Flow

  • A know-how of the ins and out if statements, and loops in addition to the way they need to be implemented is vital for correct behavior of your program.
  • The candidate should also have apt knowledge about the operators and be able to introduce various characters in the code.

d). Spring Framework

  • Spring-Beans: If you have to implement the Spring Framework, then the objects which form part of your primary application and managed in the IoC are the beans.
  • Spring-AOP Analysis: Aspect-Oriented Analysis also helps the Object-Oriented Programming by giving it increased behavior to code which is already there without any modifications.
  • Spring-Test Analysis: The developer should precisely know what exactly needs to be tested in an application.

e). Hibernate

  • The knowledge of Hibernate Query Language used with the framework is also essential.

Conclusion

Thus, the choice of a Java Developer for your business is a vital decision and has to be taken after a lot of forethought. You should not only seek basic Java skills and specialized knowledge but also look for flexibility in approach and problem-solving ability. It is advisable to invest a suitable amount of time in the process to arrive at an informed decision.
