Premium questions with real-world problems

The Embedded Systems and C++ test assesses candidates' knowledge of embedded systems and the C++ programming language.

It's an ideal test for pre-employment screening. A good embedded systems/software engineer needs to know how to design, develop, test, and maintain embedded systems. They need to be familiar with hardware used for embedded systems, technologies used for connecting embedded devices and know how to develop software required to run the system using the C++ programming language.

This online test requires candidates to answer multiple-choice and fill the blanks questions about hardware and software used in embedded devices, and to solve coding problems in C++.

TestDome is trusted by businesses large and small

Our sample questions are free for companies to use on a trial plan. See more about our premium questions for paid plans below.

Merge Names

10min

Easy

CODE

C++ Arrays Public

Implement the unique_names method. When passed two vectors of names, it will return a vector containing the names that appear in either or both vectors. The returned vector should have no duplicates.

For example, calling unique_names(std::vector<std::string>{"Ava", "Emma", "Olivia"}, std::vector<std::string>{"Olivia", "Sophia", "Emma"}) should return a vector containing Ava, Emma, Olivia, and Sophia in any order.

Quadratic Equation

CODE

C++ 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 elements of the pair. 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.

Binary Search Tree

CODE

C++ Algorithmic thinking Recursion Tree Public

A three-node binary tree.Binary search tree (BST) is a binary tree where the value of each node is larger or equal to the values in all the nodes in that node's left subtree and is smaller than the values in all the nodes in that node's right subtree.

Write a function that, efficiently with respect to time used, checks if a given binary search tree contains a given value.

For example, for the following tree:

  • n1 (Value: 1, Left: null, Right: null)
  • n2 (Value: 2, Left: n1, Right: n3)
  • n3 (Value: 3, Left: null, Right: null)

Call to contains(n2, 3) should return true since a tree with root at n2 contains number 3.

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.
