Exactly. I'm in a completely different field than the demographic of HN users; however, easy apply does give me the ability to apply to a bunch of random positions at various tiers. Now I've never had an offer from LinkedIn and a handful of interviews out of the 500+ applications but it does give me the the ability to apply quickly. For cool companies I find that have jobs I am not qualified for I just book mark them into my companies bookmark and periodically check or reach out to a recruiter.
I can do 10 applications in 10 seconds for various tiers of jobs and various jobs in different locations and get an idea of what kind of interviews I can get going forward.
But yeah, I don’t get more interviews. I just get to lazily spam.
