Screen your job candidates
the same way as Google and Facebook

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

Need high-quality live coding tests?

We have a variety of tests 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 your custom question is as easy as adding a few source code files. Answers are automatically evaluated using simple test methods.

Want to test yourself?

Practice with public questions and improve your interview skills for free. Premium questions are only available to companies, sorry :(

Need a good developers?

We are building a platform where you will get access to top developers that passed our tests and who explicitly opted-in to be connected with recruiters.


Superior Screening

Superior Screening

Use our tests and the platform to detect A+ programmers early in the employment process. Our tests can measure code correctness, memory consumption and execution speed automatically.

Save your time

Save your time

Technical preselection saves time on reading resumes, phone screening, and bad interviews. Companies like Google or Facebook use live coding tests to screen millions of candidates per year, making sure that they only spend time on qualified 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 with testing 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 basic required knowledge in the shortest time. Candidates take 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 him a sample of the actual work. Science has proved that this has better correlation with work performance than indirect measures such as IQ, personality or education degree.

Cheating Protection

Cheating Protection

Classic multiple choice tests are trivial to cheat 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 give you money back 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, you need to write programs that are both correct and efficient. Additionally, you can examine answers and the coding style for every candidate.

Created by Experts

Created by Experts

All tests are hand-crafted 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, you can apply here.

Risk-free Investment

Risk-free Investment

The free plan includes 5 candidates per month. In the pay-as-you-go plan you simply pay $10 per tested candidate. No monthly subscriptions, no contracts, cancel anytime.
