Interview Questions that You Should Ask When You Hire Java Developers
In our world, people think that if they have theoretical knowledge, they also possess practical knowledge. See, theory without practice is nothing. If you want to be a skilled Java developer, you have to practice. Similarly, practice without theoretical knowledge is also nothing. You cannot code without having the knowledge of how to code.
But how can you judge whether a candidate is strong on the practical side or theoretical side of Java? Well, that can be done by asking questions during the interview. However, there is a catch to this. It is not about seeing whether a candidate is capable or not, so there is no need to ask difficult questions. Keep the flow of conversation casual, only touching the tip of every question.
Here is what you can ask from the candidate.
- Topics related to Java core
- Questions about Databases
- Questions of Multithreading
- Tools and libraries questions
- About APIs and integrations
Hire Java Developers-How to do that?
Now that you have the knowledge of what Java is and what type of skills a candidate should have, let’s talk through the steps when you want to hire a dedicated Java developer.
Choose the type of Java developer
The first thing that you need to do is decide what type of Java developer for hire you want. You can find even more details on hiring these professionals in this article. Whether you want to outsource the project or looking for a full-time developer. Or, do you want a part-time remote developer? Here are the platforms from which you can choose from:
- Freelance websites (Upwork, Fiverr)
- Recruiting Agencies
- Offshoring companies
Go through the Portfolio
Once you have decided what type of Java developer you want, it is time to check the portfolio. See whether the candidates you have selected meet the hard/soft skills of your project and what type of experience they have. If the developer is offshoring freelancers, look at the reviews of their past clients and see what they are saying.
Screening and Interview
After filtering out the potential candidates, set up an interview and screen the candidates. When you hire Java developers, ask them the interview questions (mentioned above) and see whether they are capable or not.
Hire A dedicated Java developer
