Well, you just described the process for most programmers: we want to first see if we are interested and only then schedule a phone call. Pressuring me into a phone call just nets you a generic "let me get back to you" and 90% of the time I never do.
I am not committed to their process, not to the process, you know?
You're right on the money. Plus, most people want to see if the role is actually a fit. 50% of the roles I receive are data pipeline and BI infrastructure roles. I'm on the analytics side but because SQL is on my resume, it comes up in their searches. Majority of recruiters don't know the different so of course I don't want to waste 10-15 minutes on each of these calls.
