6. How To Hire Java Developers? A Few Things You Need To Consider


When hiring java developers, remember to be specific in your requirements – java developer interview questions

Choose The Best Cooperation Model For Outsourced Java Development

If you have technical skills and require experts for specific goals, hiring a freelancer could be the easiest and the most effective option. However, if you have a long-term project with a scope that might change in the future, partnering with a software development company can work out better. One of the most important parts of partnering with another company is choosing a suitable engagement model. Learn more about models like Extended Team, Dedicated Team, and Managed Product to determine how you can benefit. In a nutshell, the right cooperation model can spare you the hassle of hiring experts and managing the development process, letting you focus on the business aspects.

Partner Up With The Right Company For Java Development Outsourcing

If you are considering working with a software development company, make sure to check its track record on outsourcing Java projects. Some case studies on long-lasting projects might be a great indicator that your potential partnership will also deliver outstanding results. A company that outsources Java programming and is good at it will gladly share its proven expertise and opinions on the subject. The knowledge and experience in your specific industry will be a big plus. Please don’t rush in choosing a partner.

Be Specific In Your Requirements

Ensure that the recruiting team is not using generic Java Developer job descriptions that don’t say anything about the actual job. Your candidates must have the specific set of technical skills and soft skills required for the job. Highlight the key technologies in your stack and your business domain that may narrow the number of candidates and help you find the right people faster. This programming language is versatile and covers a wide range of areas in web and mobile application development. You, or your technical team, need to understand what JSF, Strut, Grails, Play, Spring, and Maven frameworks are and which ones you require for your outsourced Java project. There is a chance that you will find an expert who does not possess the skills in the required tech stack. After the decision is made on your requirements, make sure that the actual interview includes questions about the development skills, tools, and key strengths (including experience in wire-frames, user experience design, or knowledge of APIs, for example).

Get Motivated Experts

On the other hand, you need to understand the motivation of potential candidates. You must understand what exactly drives experts to be a part of your company. Is it a good salary or an interesting project? Or maybe it is an opportunity for potential growth? Clearly understanding your employees’ motivations may help you keep them on the team in the most challenging situations.

Your Outsource Java Developers Need To Have A Fine-Tuned Process

Motivation is a good thing and a significant factor for the success of any team. However, the experts you add to your team must understand the product development process. If we’re talking about hiring a dedicated development team, a complete understanding of Agile principles and its practical implementation of Scrum is mandatory for maximal efficiency. Of course, they can use some other process, like Waterfall. But based on our experience, the Agile/Scrum combination is the best for any software development project. Java development outsourcing is not an exception. In case the development team you hire is not adhering to the principles of Agile, you will probably need to spend some time coaching them; otherwise, you may not get the best results due to the chaotic process.
