Applications with LinkedIn to improve your application rate
https://help.refari.work/knowledge-base/article/applications-with-linkedin-to-improve-your-application-rate
Having the apply with LinkedIn capability allows candidates to place a 'speculative application' and greatly increases the conversion rate of the job advert, it does this by allowing candidates who may not have a Resume ready to submit their LinkedIn profile for review.
You may notice such applications as having no physical CV on the application, however they will have a LinkedIn profile URL for review. In the scenario where a candidates LinkedIn profile appears relevant for the role you are working on you can of course request a written CV.
You will see this type of application presented in Refari like this 
You will also note the application email from Refari presents a link to review the Linkedin profile also.

If clients require we can turn the 'Apply with LinkedIn' feature off, but we must note that you are likely see a slight drop in the conversion rate of your job adverts.
