About what I know on UPS
Well as it goes for a preparation to be ready for a respectfull
interview at UPS is to meet the interviewer with a very good
behavior and a good self confidence about it as well a great
enthuaism of the company!
And remember people always shake hands before the interview
also after the meeting!
