I feel bad for people and adults that are having a hard time finding a job, considering I didn't have a hard time at all, and the job I have now found me.
I just happened to be in the right place at the right time, and was asked by the boss of a place called Ace Hardware if I wanted a job as a cashier. To which I immediately said yes, filled out an application, had an interview and was hired on the spot.
Of course most of my friends and the people I know think it's funny that a female is working at a hardware store, but I find the place to be amazing. Plus I get a huge discount on anything I want to buy, and so do all of my family members.
Just remember that filling out an application and returning it to the place you want to work isn't enough. After a couple of days you should be calling to talk to a manager about checking on your application. That sort of stuff shows that you are really interested in getting the job.
