Companies already get so many applications that applying is a crapshoot without a referral. I feel like this is the opposite of what we need.
A referral isn't really useful on its own. Ideally the person doing the referral needs to have the ear of the HM and followup regularly. Otherwise it's an easily missed note on an ATS.
The employers want applications so badly they are willing to post job ads that don't exist.
The need for a referral to get human eyes on your resume is a different problem that isn't made better by making every application expensive for the applicant. Poor quality applicants have more time, you might say.
