Marketing yourself has changed forever. No longer can you introduce yourself and have a two way conversation resulting at some point in employment. If you're young, you need credentials and or experience. If your not so young, you need a real good reason why you're applying for a meanial job if you're worth a crap, and a clean criminal record, clean credit record, clean driving record, business references, experience in that field, all to make $10.hr. which you can't live anywhere on.
