If you're getting so many applications that you have to apply such a harsh screen that you're likely losing most of your good candidates via false negatives then you shouldn't be soliciting more applicants to apply. This is what this thread is about - if you're saying these guys are getting so many applications they have to start just brutally cutting CVs almost arbitrarily then they definitely shouldn't be posting on HN about their vacancies. Not least because they're poisoning the well.

This is a real issue - I once got approached by a recruiter for a company, it was a good fit, I think I would've walked the interview and been a great hire - I'd heard of them before. The founder had acted like a dick head to one of my friends, I just immediately turned it down. There is a cost to very publicly treating people poorly. People don't seem to understand that these things that big companies might get away with due to scale, smaller companies cannot. People talk.
