About the test
The Data Structures and Algorithms online test assesses candidates' knowledge of software data structures and algorithms.
It's an ideal test for pre-employment screening. A good software engineer should know when and how to use proper data structures and/or algorithms to make optimized code that works when amount of data that needs to be processed increases.
This online test requires candidates to answer questions about data structures, algorithms, time complexity and algorithmic thinking in general.
Sample public questions
For the following pseudocode functions, choose the big O notation that accurately describes its worst-case complexity.
Answer the questions below regarding correct usage of data structures.
The function below is used to search for an element in a binary tree that contains linked nodes.
function treeContains(treeNode : Node, element : int) : bool if (treeNode == NULL) return false else if (treeNode.getValue() == element) return true else left : bool = treeContains(treeNode.getLeft(), element) right : bool = treeContains(treeNode.getRight(), element) return left || right end if end function
What can be said about the treeContains function?

What others say
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.
