Iff approved at interview, and they stamped your passport with I-551 stamp, you can be employed for work if you do not have I-551 stamp or green-card in hand, most employers will not employ you until you can prove you are authorized to work.
Ditto - become familiar with Homeland Security's form of employment eligibility (I always forget the #, think it's I-9). you don't need the physical green card as long as you have the other documents on the form's list of approved ID's.
Good luck, L.
