Be a Professional
In addition to your attire, don’t forget a strong handshake and good eye contact. Carry a simple padfolio with copies of your resume and a pad of paper for taking notes. Offer them your resume. Be considerate of the employers’ time (most conversations are between 3-7 minutes) and mind your manners and mannerisms. This is your opportunity to be evaluated on more than your resume. Make sure you leave a positive impression.
When you are concluding the conversation, ask if they have a business card. If not, you can ask them for their email and if it is okay for you to follow up with them.
