Here are 7 questions to ask PHP developers that make your mobile app development project quite easier. Let’s get started!

Ask Basics about the PHP language

You need to make sure that the candidate must have an excellent understanding of PHP and how it’s used in the development procedure.

Ask questions about their Past Projects

It’s important to ask the candidate about the last projects to know their proficiency. However, the project may seem very striking but ask about the part they played in the particular project. Ask them their contributions in the development part. Keep in mind that if their answers sound a little bit unclear, it doesn’t mean you should drop the idea of hiring them immediately.

Ask some Non-Technical Queries

In order to check the communication skills of the developer, it is important to ask some non-technical queries. Developers sometimes need to discuss common scenarios with other developers and non-developers so having good communication skills is crucial in the development part. This is something that helps you to find how they communicate, which is no less vital than their PHP skills.

Ask them about the coding style

There are a lot of ways through which you can check their coding style. You can use coding tests that are available online, but make sure that they are genuine world coding challenges and not some normal “textbook” related problems. You can also take their small test. Keep in mind; it’s not the last thing that matters for hiring the PHP developer. You just have to check how your candidate does the assignment and it is a chance to evaluate their work before handing them your valuable project.

Simply prepare a list of questions that help you to remember the right questions.

Ask technical questions like how to use PHP to encrypt data or ask questions about some design patterns of PHP to verify the skills.

Previous projects

Before selecting a PHP developer, it is vital to check their past work. Ask them if they have worked on some projects like yours. Check customer testimonials and reviews on the development project that the developers have worked. If the earlier clients are happy with their work, then it is clear that you are going to hire the right person for your next project.


It is quite significant to examine and measure the performance of the PHP developer you hire for your next project. The questions mentioned above will help you in hiring the right PHP developer as per your needs and requirement. Selecting the right candidate is necessary to make certain that your project will be successful and runs perfectly.

The PHP developer will be responsible for boosting the website with the usage of most modern programming methods and strategies.

So, before hiring a PHP developer for your future project, it is important to make things clear to avoid uncertainty later.
