The only person on the planet who actually cannot get a job is me. I'm the one person who is literally unhireable. I have basically no work experience, whatsoever, and I've been an adult for 18 years, will be 19 years this summer. I should be more than half way to retirement right now. Instead, I'm still trying to start life from the beginning, as if I just turned 18.
So, in a way, I can't help anyone with this question, let alone you.
I think you will get hired. I'm the one who will not. I can name to you companies that flat out told me that there is no way in h3ll that they would hire me. And yet, even they still expect someone to hire me, which I don't get, cause they, as an employer, should know better than to actually expect another employer to hire me, when they, themselves, feel that way about me.
All I can say is, keep applying. Do yard work for neighbors. Start a business of your own. Something is bound to come through for YOU.
You are doing nothing wrong in your job search. It's just difficult to find a job. In the 1800s, all we had to do was walk in, say, "Need some help around here?" And, the owner would say, "Yeah, you can start sweeping over there, and I will tell you what else to do later." And just like that, we could grab their broom, and start sweeping, and we had a job. Today, there could be 500 companies that are hiring, with 100,000 positions available, and only 250 applicants, and they need to hire someone yesterday to stay operating the way they need to operate, and you could even have exactly what they said they are looking for in a candidate, and still not be hired. That's just the way it's done today. So, it's not you. It's the system. There's nothing you can do but keep applying. What's wrong could be anything from you don't have a state required license to do said job, to they want someone with five years experience in the field when you only have six months experience in the field, to they only need one person to do the job out of 500 applicants, to they only have enough money to fill so many positions, to they have all of the workers they need, to even something as simple as they are looking for someone like Sally to fill the position, and you are more like Amy. It could be anything happening. All you can do is keep applying.
