CodeSignal

With the CodeSignal extension, technical recruiters don’t have to switch between their Applicant Tracking System and CodeSignal while scheduling interviews — instead, they can conveniently generate interview links directly from the extension while staying within the ATS. 
Recruiters can also view previous links that they have generated through the extension, to allow for copying it easily to multiple places, such as both the ATS and a calendar invitation, for example. 

For Greenhouse and Lever users, the integration is even more powerful. The CodeSignal extension will generate a “Create Interview Link” option directly within the Greenhouse or Lever ATS, which you can click to automatically generate an interview link that will be auto-filled into your ATS (for Greenhouse) or can be easily copied (for Lever). To get started, simply download the extension and log in to your CodeSignal company account. If you’re not using Greenhouse or Lever, click on the CodeSignal extension icon to get started! If you are using Greenhouse or Lever, then open a candidate's profile in your ATS, and autogenerate a CodeSignal interview link with the click of a button!
