It's not easy to prepare for a job interview,especially for people like me who doesn't know much stuff.But I will try and you can try.You need to dress up not like a cheezy pimp but more of a lady,be more classic and not carry a backpack.You will need to polish your shoes and dresses and clean up your face and brush your teeth.Then just show up and demand for a job,with a threatening way.I am sure you will get the job.
