Read your resume thoroughly to explain your professional or projects' experience
Be prepared to give a positive two or three minute summary of your professional career.
If you use a hand set phone, make sure you have charged it properly.
Have your resume, paper, pen, and a glass of water handy
Don't:
When you are on the phone, if you don't understand the question, don't pretend that you did. Ask them to repeat the question.
