Our unique test creation process

Crowd knowledge.
Zero bias.

We crowdsource test questions from multiple experts rather than relying on a single individual. This helps to minimize unconscious biases and promotes diverse thought.

Dotting all the i’s &
crossing all the t’s

Our expert community is carefully curated, covering all levels, backgrounds and specialisations. Tapping into complementary expertise ensures our tests are thorough and well-rounded.

A system of checks
and balances

We’re big on practical questions and useful knowledge. Senior reviewers and question performance data help us weed out bookish questions and guarantee test quality.

Verify candidates’ skills the easy way

Turn your skills assessments into a hiring advantage. Customize, brand and automate in just a few clicks.

Get really precise – add custom questions

Make sure your skills assessments hit the nail on the head. Easily switch between test difficulty levels, add custom questions and adjust time limits.

Automate screening with a pass threshold

With a minimum pass score, you can cut down your screening time by 86%. Decide what a successful test result is and let us do the heavy screening for you. We’ll shuffle top performers to the top of your list.

Trust the results you get with cheat-proof tests

Our skills assessment engine combines anti-cheating measures with dynamic testing. No test taker gets the same questions, and if they try something fishy, we flag the results for you.
