Be prepared to demonstrate how you will add value

Develop the ability to 'sell yourself' & the art of 'persuasion' to increase your odds of being hired 

Read your audience and the situation accurately and be self aware

Convince yourself of your qualifications through 'self affirmations'

It's not only 'what' you say but 'how' you say it

Communicate clearly and concisely without rambling
