Okay, so the issue is less Greenhouse specifically, and more generally applicant tracking systems (ATS) in general. Fair enough, I have found pretty much the same, direct internal referrals are the best way to go. Networking is about more than the Internet.

Maybe, although even direct contacts either way without an introduction or referral has been a much better experience.

I can't say without being a customer of Greenhouse myself, but I suspect they have some SaaS sauce or cross-company application data that hits me somehow for quick filtering out.
