21 interesting topics to help you kiss your next PHP job interview

PHP is a huge and wonderful programming(scripting) language that occupies a great position among web technologies.

Although it doesn't offer the most paid jobs, there are great opportunities out there which can change your life forever, either by increasing your income or by leveling up in your skills. It's worth being employed as a PHP developer.

The big issue isn't the work you might have to do, but getting the job itself. To have a job these days is a serious marathon.
I know that some of you will say, "if you are good enough, you have no problem" and others will say "you need to be lucky". No matter the position you take, one thing is usually common: Interviews.

Google "Job Interview" and see the number of results and how businesses take this very serious. Integrating a company is like being adopted as a child. It's a challenging phase for both the host family and the guest. It's, therefore, important to make a good choice of the child: A good child.

And the first opportunity for you to prove yourself is through an interview. That's why in this post I will be sharing with you some topics and points you should seriously consider before applying for any PHP job.

Before I list them, let me share with you something I recently noticed about interviews:

  • People who interview you are not the ones to decide of your employment
  • people who interview you have a guideline to follow from the head
  • People who interview you probably never coded for real*
  • People who interview you tend to compare themselves to you
  • People who interview you want you to forget your dreams and embrace theirs

So, these people are expecting you to give standard answers to their questions. Those are real traps you can fall in at any time, and that reduces your chances to succeed. But, you can still do something about it.

As a PHP developer, I have gone through many job opportunities and tried to find out what interviewers usually have as guidelines when it comes to PHP jobs. I believe by learning them it will be like learning pass-questions for an exam.

In this post, I will share with you some topics I think you need to learn or be informed about before attending a PHP job interview. It will increase your chance of winning your next job.

Aside from the general syntaxical knowledge of PHP, you need to know PHP community, trends, tools, best practices and some extraordinary things which can be done with PHP but that aren't common:
