I'm curious as to whether other roles and industries see a similar signal to noise ratio. I wouldn't be surprised if a lot of people are just applying to every job that's listed in their current location or where they want to live.
I'm a native Swift developer, with over 30 years' experience programming Apple devices, but I have also written a lot of PHP (backend) stuff, and Web sites.
A few years ago, I spent a few months, learning Android, and decided I didn't like it, but I do have Java and Android Studio in the mix.
I often get recruiters, trying to match me with Web design or C# (nowhere in my stack) jobs.
I'll still get pinged by recruiters for a senior network engineering job in Idaho or some such.
