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.

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

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.
