Screen your job candidates
the same way as Google and Facebook

Ask candidates to write real code, before calling them for an interview.

Need live coding tests?

We have a variety of online programming tests in subjects ranging from web development to databases and algorithms. Candidates need to write code to solve real coding problems (see work sample testing). Public questions are available for free, while premium questions are only available on a paid plan.

Want to create custom tests?

Adding a custom question is as easy as adding a few source code files. Answers are automatically evaluated using simple test methods; see our sample question.

Want to test yourself?

Practise with public questions and improve your programming skills for free. Or solve one of our public tests, and if your score is good, you will get a certificate of achievement. Premium questions are only available to companies, sorry :(


Superior Screening

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 your time

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

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

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.

Work Sample Testing

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.

Cheating Protection

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.

Code doesn't lie

Code Doesn't Lie

Even if the code works, that doesn’t mean it is good. To achieve a top score on our tests, a candidate needs to write programs that are both correct and efficient. Additionally, you can examine the answers and the coding style for every candidate.

Created by Experts

Created by Experts

All tests are handcrafted by domain experts and calibrated by both junior and senior programmers. If you are interested in making money as a content creator or as a paid calibrator, .

Risk-free Investment

Risk-free Investment

The free plan includes five candidates per month. In the pay-as-you-go plan, you simply pay for what you use, there is no monthly fee. All plans can be canceled at anytime.
