I once got not that bad advice - apply for jobs you dont really want or dont care if you dont get it, but you have some qualifications.
Like idk call center where you need english or retail or something like that (where you dont need a lot to get called for an interview). practice beforehand ofc but it will help you a lot with confidence and learning how to speak in an interview. You will also see how the process goes. (you might actually get the job this way)
and on no experience part - lie how you want to grow with them, learn from them etc. maybe try to get an intership, depending on the position you are aiming.
i'm 22 and i never had a job and i'm scared to go and look for one bc i have zero experience at all and zero confidence. Anyone like me ?
