Source: I don't do this, and basically never get a call back from anyone using Taleo, but almost always get call backs from Big Tech/startups with humans that look at resumes (tbh I suspect my pdf format also causes issues here).
Also, what is a tech company to you? Does making SW & HW scanning and test devices for the automotive and heavy industry not count as "tech"? I feel like SV has stolen the word "tech" from "technology" to mean "VC funded mobile web start-up founded to make money on skirting regulations and tracking users" the same way cryptocurrencies have stolen the "crypto" from "cryptography"
That being said, a lot of my roles have come through external recruiters so maybe that's what saves me.
It's odd that Ireland wouldn't see the same spamming though, given that we're an English speaking country with lots of tech roles.
Also external recruiters don't use autolatric filtering systems since they usually just fish people via LinkedIn. It's mostly the companies own application websites that use these systems as they're the ones getting spammed, not the external recruiters.
Which is odd, maybe something to do with the fact that Ireland isn't in Schengen?
