What to Look for When Hiring Java Developers

Due to its importance in creating and maintaining apps, maintaining the design and functionality of websites, and numerous other uses, coding has become a hot commodity. Coders, specifically people with Java experience, are even more in demand. As a recruiter or hiring manager, how do you know what makes an excellent Java developer?

Look for Knowledge AND Experience

Programs like Java are constantly evolving, and coders need to be up-to-date on the latest version. Applicants with experience from years ago aren’t likely to make good developers for your company. Neither will applicants who are fresh out of college. What is learned in college is different from experience gained through real-world application.

A good developer will know the current Java tools and how to use them. However, he or she should also be aware of the libraries at their disposal. Consider this added element in your applicants’ resumes because it helps with an understanding of how every aspect of Java functions. Being able to utilize all the functions of Java will save developers and companies time.

An Understanding of Key Concepts is Crucial

– Model-View-Controller (MVC) Pattern

A process used to manipulate data. The ‘Model’ is the data, the ‘View’ shows how the data is presented, and the ‘Controller’ monitors the other two for any changes.

– Dependency Injection

Inserting objects of the same kind as the initial dependent object to keep it from having to make those objects themselves.

– Java Memory Model

A representation of how Java interacts with memory code in a computer’s system.

– Multi-Threading & Concurrency

Multi-Threading uses multiple (or concurrent) executions within a program to allow for different actions to occur at the same time.

– Data Access Object (DAO) & Java Database Connectivity (JDBC) Patterns

DAO patterns separate data at different levels. JDBC is a Java Application Programming Interface (API) that manages all the elements in a database. JDBC uses DAO patterns to segregate data.

Some things to ask Java developers:

  1. Are you versatile in different projects, and can you create Java applications to meet certain project requirements?
  2. Do you have significant experience with large databases?
  3. Have you worked with software integration?
  4. Do your skills include different areas of project development?

Questions like these can help you gauge their potential worth for your company before you hire them. Adaptability, experience, and multi-tasking are excellent—sometimes crucial—skills that developers need. It also helps make a stronger connection between employers and employee candidates when the former can rely on the latter’s skills.

All of the Above

While experience is the most important thing you should consider as a recruiter or hiring manager, relevant certificates and skill levels in many areas are beneficial qualities as well. Finding good Java developers who fit all of these categories to your satisfaction could be challenging due to the ever-growing applicant pool. Since the transition to primarily remote positions as a result of the COVID-19 pandemic, there has been a drastic increase in applications for coding positions. Train yourself to look for a good combination of skills, experience, and flexibility that will benefit you in the long run.
