Great: I'm really pleased for you, and I hope you have a fulfilling career. But all you're telling me is that if you don't respond to the invitation I've sent you then you don't want the job I'm advertising that much. And guess what? I'm selecting against people who don't want the job I'm advertising that much.
Now here's an interesting thing that I've spotted before on HN: the silent majority have upvoted me, but a few commenters have taken me to task. Clearly I'm not suggesting that the majority are always right (the majority of people used to think the world was flat and look how that turned out), but it's certainly worth further consideration.
In reality, while software development skills are in high demand, there's also a very high supply segmented across different skillsets and industries (and yes, in lots of industries being a software and domain SME is important). Companies have had lots of success using take home projects or short assessments for technical skills like HackerRank to separate both the wheat from the chaff and remove those who don't want that particular role that much (as you said).
At the moment we get few enough applicants that I'm fortunate enough to be able to talk to all of them. What has surprised me is that a relatively high proportion simply don't respond to that invitation. The numbers aren't yet anywhere near high enough to feel confident here, but it does seem - at least superficially - like there might be a correlation with weaker applications here.
Be aware that most of those are basically a scam. Trying to force you into some random job just so they can get the provision.
And yeah, I have a job in software development.
