How To Hire Java Developers: 7 Steps to Follow

Here is a step-by-step tutorial to help you hire Java developers who align well with your team.

Step 1: Build An Evaluation Form

Before diving into hiring Java developers, you need to define what you need about an ideal candidate. You can do it by building an evaluation form which can help you objectively evaluate candidates throughout the process.

Here’s what to include in your evaluation form:

• Technical skills: Include Java fundamentals (ORP, data structures, algorithms), JDBC, frameworks, libraries, Java development skills, knowledge of Java-based applications and understanding of version control systems.
• Experience: Define the level of experience you’re looking for (junior, mid-level, or senior). Remember to provide clear criteria or expectations for each level. If relevant, consider specific project types (mobile, PC).
• Soft skills: Detail criteria for soft skills like communication, teamwork, planning, problem-solving and time management.
• Samples: Provide guidance on what types samples should include in a resume such as projects carried out, the role the candidate played in each project, experiences and skills learned, any notable achievements, etc.

Pro tip: It is important to detail the proportions for each category in the form. This reflects the relative importance of each skill or quality. To make it easier, you should clearly determine how much technology skills account for and how much soft skills account for the total. For senior level candidates, technical skills may be more valued, while the ability to absorb and work according to a plan may be more crucial for beginner and mid-level applicants.

Step 2: Create A Detailed and Captivating Job Description
