Reviewing candidate code

When a candidate finishes a test and you receive their test report, you can find out more about how they code and problem solve by using the code playback feature.

CodinGame makes a recording of all your candidate’s coding activity during a test. You can watch how your candidate built their algorithm, when they left the environment, when and what they pasted from external sources, and what happened when they ran their code. 

To see this, first go to your candidate’s detailed report and pick a programming question you want to know more about.

Then click the play button ▶️ at the bottom of the screen to see the playback.

The playback screen with candidate code at the top and a highlighted "play" symbol at the bottom.

Speed up or slow down the playback (from x0.5 to x8 seconds) by clicking the number in the bottom left. You can also pause the recording at any time. 

The timeline has different color segments:

  • Green when your candidate runs or submits code.
  • Orange when your candidate is writing code.
  • Red when your candidate pastes code.
  • Dark grey when your candidate leaves or comes back to the test.
  • Light grey to show how long your candidate spent outside of the CodinGame test.

Click Run this code to run the candidate’s code at any time.

The playback screen with candidate code at the top portion of the screen. In the top right an arrow points to the "run this code" button".

You will then see the code editor open in a new tab where you can test your candidate’s solution by selecting Test Your Code.

The code editor for a particular coding exercise is displayed along with candidate code. An arrow points to the bottom of the screen at the "test your code" button.

The result appears in the Console output.
