What do I have to do in order to become a Retail sales consultant with At&t?

Just be very professional. Dress professionally and try to talk with tone and politeness. Everything you say should be intelligent and with sincerity. Don't slouch and always have eye contact, don't focus on their eyes but have eye contact. Make sure you're cleaned up and if it's a guy that interviews you make sure you give a little bit of a giggle every once and a while, it's more of a play on type of thing with guys. Make sure you have that friendly feeling and fun to be with so that you don't seem to be like a person that has something poking them in the back. Your resume should also look very good, even if you don't have work experience.
