It is an impossibly tough job market (which started in late 2022 and has had no recovery since).

Third-party AI interference has made everything worse through the imposition of cost on everyone. (Fraudulent Ghost jobs/Candidates tortuously interfering)

There are some things you can do with your CV but the major issue is in getting through the door and talking to someone. Most places have outsourced their HR departments to AI, and the problem with that is the black-box nature of weights may be (and probably is) discriminating against protected classes.

The CV to cold call ratio has gone from 1 in 100 to 1>1500. You may get lucky if you somehow manage to find a place that has a process that ignores this and goes physical. Some are going back to this now.

With that said, the gap in time isn't going to help. There aren't a lot of jobs.

If you continue to see poor callback ratios, first verify your phone is working properly. In many places too, calling service reliability has degraded without people realizing it.

You'll need to arrange to test your phone like any call center would.

One regular timed call, one regular text message, twice daily with a 5-10 minute delay threshold on the texts and voicemails. Also one randomized call from a random external number.

Test voicemail as well. Calling has been failing for some people in the part of the failure domain that is interrupt driven (the part where you never know you missed a call), and the voicemails may not show up for days to weeks.

I've heard from others and seen this myself on both AT&T, Verizon, and third-party VOIP-based networks. Its a real problem that is absolutely crazy-making. Tickets get opened, 30 days later closed without resolution or explanation. Its been an ongoing problem for at least a year and a half now and we regularly see calls dropping/being degraded on a non-insignificant count on weekly basis.

If you can't find work in your given profession, you may need to look at retraining to other work. Usually 2 years is more than sufficient time before making this choice. Its horrible to have to make a choice like that but that is what happens when you have coordinated layoffs in an oligopoly industrial environment.

Competent people naturally have options and go where their efforts are rewarded economically.
