If you are on time for your interview and dressed to perfection, but your personality is insipid and withdrawn, expect NOT to be the winning candidate.
Your personality should exude enthusiasm, confidence, respect, knowledge, gratitude, and focus.
When speaking, be sure to do the following:
At the end of the interview, thank the judges for their time and consideration. Leave with firm handshake, eye contact, and a smile. Also, consider sending a follow-up thank you note for the opportunity to meet with them.
