LinkedIn have an automated rater for applications. Any that their tool consider to not be a fit is automatically tagged "Not a fit" and color coded accordingly, making it very obvious. It's probably based on the location of the applicant Vs the location the job specifies and the skills on their LinkedIn profile.

My own experience when posting jobs was that 70%+ of applicants were rated "Not a fit" and that it was an accurate rating.

This means that when the ad poster goes in to look at the applicants they can discount a huge proportion from the start as the list is already triaged.

100s does not really mean 100s.
