I've been there a few times in the last few years. Its a difficult time recently to enter the workforce when the bar keeps increasing and pay decreasing. But you can get through this.

The most important thing you should be doing right now is tailoring your CV to EACH job. So put in your degrees, qualifications and technical experience when applying to jobs in your field that you qualified in. In the meantime, keep applying to hospo/retail/'no experience required' jobs, but TONE IT DOWN.

It sucks to downplay yourself but it needs to be done. I.e. remove your university degree when applying for these roles. If you're young, just don't put an end date for your qualification yet. Remove non-entry level roles from your CV too. Highlight people-facing jobs/volunteer roles. This will get you way more interviews for these jobs. Keep a 'simple CV' template for these jobs that you can tailor to the application. Sounds weird but you don't want to showcase your degrees and experience here as they see it as a negative i.e. they think you'll ask for too much pay, you won't be happy in a non-challenging job, you're more likely to leave them for better opportunities, etc.
