Greenhouse Recruiting uses Google's reCAPTCHA to help keep robots and spammers from easily applying to jobs on your job board.
Depending on your organization's spam protection settings and how reCAPTCHA interprets a user's activity, they may experience either an invisible reCAPTCHA or be asked to verify their email.
Invisible reCAPTCHA
Invisible reCAPTCHA analyzes activity on a job post, like mouse movements and typing patterns, to determine if a user is a robot. This security feature helps ensure that only legitimate applications are being submitted to your candidate pipeline.
When an application is submitted, a graphic with the words "protected by reCAPTCHA" appears briefly as reCAPTCHA analyzes the activity on the submission.
After a few moments, if the feature determines that the submission was created by a real candidate, the image is dismissed and the application is submitted. In some cases, a user may be asked to submit a code from their email to verify their identity.
Spam protection settings
You can customize the sensitivity of your spam protection for each of your job boards. Go to Configure > Job boards & posts, then select your job boards. In Boards settings, scroll to Spam protection. Then select your desired level of spam sensitivity.
Depending on your spam sensitivity setting and the user's score, a user may be asked to verify their email before submitting their application.
Stricter spam sensitivity settings require higher scores. They'll block more spam but will add more friction to the application process for some users.
