applying for apprenticeship and have never had a (real) job, i have good HS grades. i was a tutor for math and physics but it was like a fake business, cash only payment and shit. for 2 years however idk how that will help.
you're better off going to a hotel bar on a weekday and finding someone in sales and becoming friends. then you will get a job from them.
or if not going into sales go into any local pub / bar and befriend someone with influence.
applying through transactional portals is not the play and has no advantage.
