Let's assume these are 700 _qualified_ applicants and its for a programming role. I.e. their resumes and applications have passed the most basic of filters of "claims they can do a similar job" and "is probably a real person".
How about... * Filter candidates if they have typos in their resumes
* Filter candidates who don't explicitly state that they leverage your tech stack
* Filter candidates who excessively job hop
* Filter candidates who have below some minimum of professional experience
* Filter candidates who live far from the workplace
* Filter candidates, for a remote role, who live in HCOL area
* Filter candidates who put objective statements in their resume
* Filter candidates who don't put objective statements in their resume
* Filter candidates who don't have a link to some online portfolio (Github, personal blog, etc.)
* Filter candidates who don't contribute to open source
* Roll a dice
The imagination is the limit!
