Premium questions with real-world problems

The HTML/CSS, JavaScript, Ruby, and SQL online test assesses candidates' knowledge across the whole Web stack from HTML, CSS, and JavaScript on the Web front-end over Ruby on the back-end to SQL for data access.

It's an ideal test for pre-employment screening. A good Ruby full stack developer needs to be familiar in a wide range of technologies.

This online test requires candidates to solve coding problems and find and fix bugs in multiple technologies.

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:

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

For example, calling unique_names(["Ava", "Emma", "Olivia"], ["Olivia", "Sophia", "Emma"]) should return an array containing Ava, Emma, Olivia, and Sophia in any order.

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.
