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.
I make $170K/year now. There have been lean times/years when I had to work in overqualified postions for meat brains like you. Such is life. If I want a job I can get a job, the BS HR people won't stop me.
