I'm now happily employed, but I went through a layoff that took three months before I finally found my current job.

During that time, I sent out 91 job applications. Of those 91, eleven of them sent me an automated response saying they'd received my application, and nothing after that. 22 of them didn't even send that automated response. I didn't keep track of those that I got an initial contact from, but then got ghosted, but there were a few of those as well.

Do better. Have some respect for the people who are spending time applying to the jobs that you posted. I know hiring managers and recruiters are hardworking and have a lot of applications to go through. But, you could at least have the respect to have a form rejection letter to send out when you drop a resume in the rejection stack.
