About the test

The Web Developer online test assesses knowledge of front-end web development skills (HTML, CSS, and JavaScript) through a series of live coding questions that test the ability to implement and style a user interface. Tasks on this test are executed inside the Google Chrome web browser.

The assessment includes solving work-sample tasks such as:

  • Defining HTML elements and their attributes, and applying CSS styles to them.
  • Handling user events and manipulating DOM to build responsive web pages.
  • Serializing to/from JSON and making AJAX calls.

A good front-end web developer needs a solid understanding of HTML, CSS, and JavaScript in order to create modern, interactive, and responsive websites and user interfaces.

A gaming company is working on a platformer game. They need a function that will compute the character's final speed, given a map and a starting speed.

The terrain on which the game character moves forward is made from various pieces of land placed together. Implement the function calculateFinalSpeed which takes the initial speed of the character, and an array of degrees of inclination that represent the uneven terrain.

The speed of the character will increase or decrease proportionally to the incline of the land, as shown in the image below:

Image showing the increase and decrease of character speed.

The magnitude of the angle of inclination will always be < 90°. The speed change occurs only once for each piece of land. The function should immediately return 0 as the final speed if an incline reduces the speed to 0 or below 0, which makes the character lose 1 life.

For example, the below code:

console.log(calculateFinalSpeed(60, [0, 30, 0, -45, 0]));

should print:

Element Spacing

A website features a menu with multiple menu items. However, the borders and spacing between and within these items are not properly styled.

Update only the CSS styles for the menu-item class so that the website looks like the image below:

All borders have a thickness of 2px.

What others say

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.
