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
The ways C# and Java are written, deployed, and tested are vastly different and if you don’t have that experience it’s not trivial to learn.
The market isn’t going to support changes like this anyway. Employers will still want actual experience.
