The Go/Golang online test assesses candidates' knowledge of programming in Go language and their ability to leverage commonly used built-in functions.

It's an ideal test for pre-employment screening. A good Go developer needs to be able not only to solve problems using Go as the programming language but also recognize when to take advantage of its rich set of built-in functions.

This test requires candidates to be able to solve coding problems in Go and find and fix bugs in Go programs.

Go Slices Public New

Implement the uniqueNames function. When passed two slices of names, it will return a slice containing the names that appear in either or both slices. The returned slice should have no duplicates.

For example, calling uniqueNames([]string{"Ava", "Emma", "Olivia"}, []string{"Olivia", "Sophia", "Emma"}) should return a slice containing Ava, Emma, Olivia, and Sophia in any order.

Go Arithmetic Public New

Implement the function findRoots to find the roots of the quadratic equation: ax2 + bx + c = 0. If the equation has only one solution, the function should return that solution as both results. The equation will always have at least one solution.

The roots of the quadratic equation can be found with the following formula: A quadratic equation.

For example, the roots of the equation 2x2 + 10x + 8 = 0 are -1 and -4.

Numeric Input

Go Interfaces Public New

User interface contains NumericInput control, which accepts only digits.

Extend NumericInput structure so that:

  • It implements UserInput interface.
  • Add(rune) should add only decimal digits to the input. Other runes should be ignored.
  • GetValue() should return the current input.

For example, the following code should output "10":

var input UserInput = &NumericInput{}
input.Add('1')
input.Add('a')
input.Add('0')
fmt.Println(input.GetValue())

Pass/fail grouping

Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.

Full customization

We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.

Cheating protection

Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.

Candidate reporting

Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
