It’s critical to hire the greatest developer for the job because he or she can make or break your company. Here are ten characteristics to look for in a Java developer that will help your company prosper in today’s competitive industry.

1) Look at the Java Developers with Experience

Whether you like or dislike an application, it’s always a good idea to look at some of their previous work. This will reveal their coding ability as well as how they collaborate with others. Instead than asking them to describe how something works, you may ask them to bring examples of code they’ve created so you can look at it for yourself.

Keep in mind that top java developers are in high demand, therefore you may have to pay a higher fee than usual to get their services. But keep in mind that you get what you pay for! If you want something cheap, inexpensive isn’t going to cut it if they don’t know what they’re doing or can’t give quality code. You may have to spend a little extra money, but it will be well worth it if your app begins to work well after launch day.

2) Get Them to Do an Assignment Before Hiring Them

Before bringing on a new developer, have a look at how they work. Request that they complete an assignment or a project for you so that you may assess their abilities. Inquire about how long it took them and any challenges they encountered.

Before hiring someone full-time, this will offer you a better sense of their capabilities. You can also seek references from other developers with whom they have collaborated. They may be your competitors, but they’ll usually be eager to answer your questions truthfully because it means you won’t hire them away! Also, instead of asking too many specific questions with easy answers online, inquire about their approach and style to gain a more true picture of their abilities.

3) Talk to Their Previous Clients

There are a lot of excellent developers on the Internet, but nothing beats witnessing their work in person. Examine what they’ve made and check if it fulfills your requirements before making an offer. If it does, have them come up with a couple solutions that fit those criteria. It can be difficult to express exactly what you want without putting something in writing or providing examples, so consider yourself lucky if they can come up with more than one solution to your problem.

4) Check Their Website/Portfolio

Checking at a developer’s website and/or portfolio should be one of your first actions if you’re in charge of hiring them. Don’t simply look at their most recent work; go back and see how they’ve changed over time.

When reviewing candidates’ work, keep in mind that you’re not only looking at their coding skills; you’re also looking at how they communicate and interact with others. Examine their team chemistry as well as their business expertise. Consider whether you’d be glad to have your company’s name linked with their efforts.

5) Ask For References

Ask to check their portfolio and test out their work before hiring someone to undertake Java development. A portfolio is a fantastic method to get a sense of how they think and the types of projects they enjoy working on. Reference checks can help you determine whether or not they can be trusted, as well as provide you the opportunity to speak with others who have worked with them in real-world situations.

Beyond references, trust your instincts: Whether it comes to recruiting individuals, you’ll know while something feels right or wrong, so follow your gut when you’re interviewing candidates (and perhaps hold off if something doesn’t feel quite right).

6) Assess If They Can Solve Problems on Their Own

When recruiting a developer, one of my first questions is whether or not they can think critically about their work. Inquire about an app they’ve worked on and how it functions. Allow children to solve problems on their own for a while, then follow up with questions about what they would do differently or why. You want to determine if your applicant can discover flaws in an app or suggest ways to improve it without your help.

7) Check If They Know the Latest Technologies

Don’t recruit people based on their experience; instead, hire people based on their potential. However, it’s critical to ensure that your candidate is knowledgeable about all of today’s cutting-edge technologies. Look for applicants that have experience with NoSQL databases and CSS preprocessors; even if you don’t intend to use these solutions right away, hiring an expert will save you time understanding them later.

8) Ask Them How Often They Update Their Skills

You’re hiring a programmer’s future as well as their present when you hire them. So, how do you know if they’ll be worth anything in five years? Inquire about how frequently they stay up with new technologies. Ask them how often they maintain their abilities, especially if you run a website that will need to be updated on a regular basis. It may appear odd at first—most candidates will assume you simply want to know what languages they speak—but it’s actually pretty crucial.

9) Have Them Code on Paper (instead of whiteboarding)

The issue with hiring someone with insufficient experience is that they may not perform as well as a seasoned developer. Ask how many hours each week they spend on personal projects and learning new things about their career to guarantee you’re hiring someone who will continue to grow and learn.

You should probably seek elsewhere if they say anything less than 20-30 hours. Those who devote more time to learning new techniques, languages, or frameworks will naturally progress as developers, whereas those who engage in minimal outside-of-work activity will not.

10) Ask Them How Many Hours per Week They Spend On Learning (and not just coding!)

By investing in their own knowledge and abilities, a developer’s value to your organization can be quickly improved or lowered. Don’t merely inquire about a person’s previous job responsibilities to determine whether they have what it takes to succeed as an employee.

Inquire about what they do in their spare time. You’ll know they’re passionate about learning new things and developing themselves if they spend the majority of their leisure time on programming classes or books, which is always a good indicator!
