Would your college give you the chance to work with career counselors to aid you in seeking the right fit for employment?
I once had a job lined up for customer service then had the rug pulled out my starting day because of perceptions of being quiet, which I am. Oddly, I've since worked a variety of jobs where that's actually one of my finer points, loads of positive feedback through the years. I know how to listen. Customer service isn't sales, ya know?
I hate it when employers give tests. They really don't mean much. I literally occilate on the Introvert/Extrovert scale. :\
I don't know if that helps. I loathe being boxed in and categorized.
