Send as many applications as you can, yes, but ensure you’re spreading them out across companies. Also, if you have a social network, leverage it as much as possible. Or, speak with recruiters in your field.

I have decade+ experience in my field and only got ~5% response rate over a year. In fact, my now boss bypassed their HR to hire me because they couldn’t manage thousands of applications.

The job market fucking sucks right now.
