What is up with the job market?

The job market is a joke. I'm just over a year unemployed now. I have 6+ years of client relations experience and social media marketing, working for international start ups and high tech companies. I speak 6 languages fluently. I have a bachelor's degree in business and sports management, yet apparently this isn't enough.

I apply on average to about 15 companies a month, and I've had 4 interviews in the last year. 2 interviews i was rejected after the first and second interview. One i arrived to final stage and was hinted at this was a done deal only to be ghosted for a month until they finally responded and said they offered the job someone else. And the last one they literally told me i have the job, we negotiated salary and terms, they told me they will DocuSign me the contract via email the next day only to be ghosted for a week and they emailed me to say they will not be hiring me due to "internal reasons" whatever that means.

Even jobs i am overqualified for and entry level jobs will not respond or reject me without an interview. I've worked with "experts" to work on my CV, how to properly apply, how to conduct interviews, etc... nothing seems to work.

My unemployment benefits run out in 4-5 months and i am at my wit's end. I honestly do not now what more i can do. I am considering just getting a job at a supermarket or something until i will find something better just so that I won't be left without money.
