Admittedly I've not job hunted recently. Are things really just that bad?
I applied 4-5 days/week for 16 months and finally got a fully remote job, with a salary commensurate with what I had before.
The job I applied for was alive for less than 24 hours. They got 1,000 resumes. I just happened to be first and early.
I applied and interviewed at FAANG too.. they said they got 1,000+ resumes on day one alone, and they were screening 20 candidates for the one role.
If you've sent 500 resumes.. that's not enough / "a lot" nowadays.
It seems to me that most job posters don’t even look at resumes anymore. I tested this by having logs for when the resume link is hit
