CSA sends this JSP i.e. Job Skills Profile to potential candidates as a link.
And when the candidates receive the link they can on the screen see the skills required for the job and against the skills that think they have indicate their proficiency. In this manner, there is an application of mind by the candidate on the skills requirement for the job and do not send off the resume with a cursory look given to the JD. Second, this is sort of a self assessment (though there is possibility of one inflating the proficiencies). Third, very importantly since all the potential candidates are applying in the same structured form, skills of the candidates are easy to analyze.
