A note of thanks
An acknowledgement that you’re there to learn
A statement about what you can bring to the company
For example: “Thank you for taking your time to meet with me today. I’m excited to learn more about your social media manager opening and how my years of designing and managing social network campaigns will be of help to you.”
On your way out, place a business card in front of everyone and offer a handshake. This is a small, but important, act. Use only quality business cards and again, look them in the eye and smile.
