During the first recession in 1981 I had the college resume and the dumb resume. It isn't hard to figure out which one to use. I meet a meat brain like you I know what to do.
Since you have elaborated and given a little work history, it does sound like you know a lot about looking for work, and have developed tricks and a talent for talking yourself into new, low quality jobs that don’t last.
On the other hand maybe you didn’t fool all those HR people and “meat brains” after all.
There’s nothing jerky about it. A hirer needs to know what they’re looking for and who fits the bill. Many are the resumes I’ve seen where I said “if only we were planning on paying this position 10 to 20 grand more”. They were great candidates for a 2 or 3 position, but we were hiring a 1, you can’t go putting a guy with 15 years of experience in a 1 position at 1 pay, you won’t keep them. Nothing meat brain about it, the meat brain is being in a position where you’re automatically the enemy of the people you want to hire you. Which is probably why you wind up dealing with HR a lot from the other side of the desk. 99% of my dealings with HR the last 20 years I’m on their side of the desk as we’re deciding who to hire.
