About the test

The WordPress online test assesses knowledge of creating and customizing web sites with the WordPress CMS and the PHP programming language. 

The assessment includes work-sample tasks such as:

  • Working with plugins and themes to customize a website.
  • Configuring a Wordpress instance to tune performance and control access to features.
  • Implementing a function that serializes to/from JSON.

A good WordPress developer needs a solid understanding of the WordPress CMS and the PHP programming language to create websites, as well as know how to configure and customize them using built-in WordPress features.

Higher Order Function

As part of a data processing pipeline, complete the implementation of the make_pipeline method:

  • The make_pipeline method should accept a variable number of functions, and it should return a new function that accepts one parameter $arg.
  • The returned function should call the first function in make_pipeline with the parameter $arg, and call the second function with the result of the first function.
  • The returned function should continue calling each function in make_pipeline in order, following the same pattern, and return the value from the last function.

For example, calling make_pipeline(function($x) { return $x * 3; }, function($x) { return $x + 1; }, function($x) { return $x / 2; }), and then calling the returned function with 3 should return 5.

3 min
Performance Tuning

Recently, the site became very slow in peak hours, when the pictures are requested very often, overloading the network.

Which of the following options are likely to increase the performance of the site enough for the peak hours to be fast again?

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
