Sick of nepotism in job interviews

17 years old and after my SIXTH job interview for a part time job in a shop, I thought it had gone pretty well. I saw a girl I know who had also interviewed just before me. She was dressed in a t shirt, jacket and tracksuit bottoms, and honestly her entire extended family must have been waiting for her, and they all gave her a big hug and a pep talk, even offering to go in with her. (We were all sitting in the one area so I heard all that was said). Meanwhile, I went on my own, I showed up 10 minutes early and dressed in smart black trousers and a white shirt. I found out I didn't get the job which is perfectly acceptable - but then I found out that this girl got the job instead of me. She's working there now and a month later, she still can't operate the tills without another worker assisting her, and a lot of the time they put her out to direct traffic in the car park Why? Because her family knows the family who run the shop.

I am so tired of nepotism among part time job interviews! I just needed a rant about this. When I got a call back, the owner told me I interviewed fantastically and that "If we were hiring more than one, you would have a job" and yet here I am, with no job in comparison to someone who showed up dressed poorly with an entire entourage of support. How the hell am I supposed to bypass this crap?
