Target Cashierr interview questions

I went through a pretty quick application process. Then I told my sister because she works there to let them know that I applied and then they called me for an interview. But I really feel like if my sister wasn't working there then I wouldn't have been offered an interview. Before that I applied like three times and couldn't get an interview until I asked my sister to tell them about me. So I feel like its true that it's all in who you know sometimes that gets you into the position that you want.
