Work Sample Testing

Test a candidate's skills by giving them a sample of actual work. Research shows that work sample testing is a better indicator of work performance than indirect measures, like education level, personality, or IQ.

Superior Screening

Our platform can detect the best candidates for you. Our tests automatically measure code correctness, memory consumption, and execution speed. And you can easily customize the tests for any language and technology.

Save time

Technical preselection saves you time so that you can focus on interviewing the most skilled candidates. Big tech companies use live coding tests to screen millions of candidates every year so that they can focus on the best.

Improve candidate quality

Some candidates might be shy or modest. Good programmers are often like that. Focus on testing their technical skills to find the right candidates and eliminate those whose only expertise is self-promotion.

Short Preselection Tests

Candidates don't like solving long, repetitive tests, and they don't have to. Our platform allows you to test the basic required knowledge in a short time. Candidates can take the tests from the comfort of their homes at a time that suits them.

Cheating Protection

The answers to classic multiple-choice tests can easily be found online. Instead of asking "What is class X used for?", ask candidates to write real code. Our premium questions are unique and we offer a refund if you find any of them answered online.
