About the test

The C# and .NET online test assesses knowledge of the .NET framework and its class library. This test includes live coding tasks in the C# programming language as it is the most used language for .NET.

The assessment includes work-sample tasks such as:

  • Working with classes, objects, and interfaces to write reusable code.
  • Implementing and properly using algorithms and data structures to optimize application performance.
  • Using the Async-Await pattern to work with asynchronous code.

A good .NET developer needs a solid understanding of the C# programming language and the .NET framework class library in order to write robust and maintainable code.

A gaming company is working on a platformer game. They need a method 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 method 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 method 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.WriteLine(CalculateFinalSpeed(60, new int[] { 0, 30, 0, -45, 0 }));

should print:

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.
