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

This online test requires candidates to solve coding problems, find and fix bugs in multiple technologies using Java as the programming language.

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.
