By default, CodeSignal interview sessions expire after 24 hours. This 24 hour period begins when an interviewer and candidate are both in the interview together. However, you can easily extend the time for your interview. This article explains how to extend an active interview session.
If you have an active interview open, you will see an “Active” tab.
You can also see all your active interviews from the INTERVIEW tab by clicking on the “REVIEW ACTIVE INTERVIEWS” button.
From here, you can go to your interview by clicking on “Go to Interview”, or finish the interview by clicking the “End” button.
To extend the time for your interview click on the timer countdown in the top right corner of the IDE. Then, click EXTEND in the pop-up window.
