Now am I supposed to bundle up all those 450 initial applications that got filtered out just to send them a nice polite email that their resumes didn't even fit the position they applied for? From a pure business perspective this is a straight waste of time. Especially as most businesses aren't going to have an automatic way to do this easily, and building that automation doesn't make my company money. But if I already happened to have some automation setup for it, then maybe sure. This part is the majority 'ghosted' applications. For the rest of the 50 I'd probably be more likely to actually send them a personalized email about the role because at least they actually fit what they applied for.
