Goodwill Production Associate interview questions

It was short. I originally applied for Production Associate but they wanted me on a different position. They toured me around the Goodwill store and introduced to some people at the office.

I got a call to meet for an interview for the following day and went. I waited a few minutes for the right person to be found and we walked around while he showed me what a donation attendant did. It seemed simple enough and I desperately need a job. After filling out a few forms for a background check and consent for drug screening I was led out and I thought everything went well. I was told the background check would take about a week and my impression was that I would then get a drug test and be working. Now its been three weeks and when I called a couple days ago they said they hadn't got my background check back and that they were still interviewing. -sigh- I am desperate for a new job and feel like I been yanked around. Why is it so hard for someone who wants to work to get a job and those who think a place is blessed by their presence and who feel they should be rewarded just for showing up well they can get jobs anywhere. It may just be this location but the process seems to take forever and I need a job now...
