No, when your credit history is non-existent, the free credit score sites will happily tell you it’s much higher than that (mine was reported as 720-740 when I lacked history), but you’ll still get auto-rejected for everything.
Interestingly, I emailed Arnold Kling, an economist writing about the subprime market at the time (2007) and he refused to believe that was happening, and insisted I must have some horrible default on my record. (I didn’t.)
A 500 credit score from a default is much better than having no history.
(I’m not the OP but was in a similar situation.)
Edit: ah, you’re the OP. Did you have that same issue, where sites would assure you you have a good credit score even as you keep getting rejected on any credit application?
[1] If they lean further on credit reports as a job applicant filter, that could turn into an even worse catch-22!
My working theory is that this case exists because they have no data to calculate and classify risk on you with.
