Work Sample Testing

To test if a candidate will be good at work, we give them a sample of the actual work. Science has proved that this has a better correlation with work performance than indirect measures such as IQ, personality or education level.

Superior Screening

Use our online tests and the platform to detect A+ programmers. Our tests can measure code correctness, memory consumption and execution speed automatically. And they are customised for every language and technology.

Save time

A technical preselection saves time on reading resumes, phone screening and bad interviews. Companies like Google and Facebook use live coding tests to screen millions of candidates each year, making sure that they only spend time on skilled candidates.

Improve candidate quality

Don’t reject candidates just because they are shy, young or modest. Good programmers are often like that. Instead, start by testing their crucial technical skills and you will eliminate candidates whose only expertise is self-promotion.

Short Preselection Tests

Candidates don’t want to solve long, 3-hour tests. And they don’t have to. Preselection is about checking the basic required knowledge in the shortest time. Candidates take the tests from the comfort of their homes, when it is convenient for them.

Cheating Protection

Classic multiple-choice tests are easy to cheat on by using Google. Instead of asking "What is class X used for?", we ask candidates to write real code. Our premium questions are unique, and we will return your money if you find any of them answered online.
