Is it possible to apply to a Job Requisition without creating an account or singing in External Career Site?
SAP SuccessFactors Recruiting Management
Current, in the way the system is designed, there won't be a way to apply without getting the candidate signing into or not creating an account if there isn't any.
However, if this scenario is desired for your business, you can't submit an enhancement request to Product Management and get this functionality reviewed and if approved, implemented within a future product release. For detailed steps on how to raise an enhancement request please follow the article 2090228 on "How to submit an enhancement request".
