About the test

The Embedded Systems and C++ online 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++.

Sample public questions

10 min

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.

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.
