Premium questions with real-world problems

The HTML/CSS, JavaScript, Python Algorithms, and SQL online test assesses candidates' knowledge across the whole Web stack. HTML, CSS, and JavaScript on the Web front-end, algorithmic-thinking skills in Python, and SQL on the back-end for data access.

It's an ideal test for pre-employment screening. A good full stack Python developer needs to be able to use a wide range of technologies, including solving back-end problems of a significant computational complexity.

This online test requires candidates to solve coding problems, find and fix bugs in multiple technologies, and analyze or design an algorithm using Python as the programming language.

TestDome is trusted by businesses large and small

HTML/CSS Borders Element size Styling Public

Every user on your website has an image avatar that is displayed when they post a comment. You want to style these images differently from other images on your site. Add a CSS class named avatar that fulfils the following requirements:

  1. The avatar's border is rounded, so that it appears as a circle.
  2. The avatar's width and height are both 150px.
  3. The avatar has a solid border, has a width of 2px, and be colored gray.

For example, the avatar in the template should look like:

Binary Search Tree

CODE

Python 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.
