You will either be escorted to the interview room, or the hiring manager will come out to meet you in the reception area. Again, take the time to introduce yourself so the interviewer knows who you are.
Offer to shake hands, even if the interviewer doesn't offer their hand first. It's good etiquette to include a handshake as part of your introduction. Tell the interviewer that it is a pleasure to meet them, smile, and be sure to make eye contact. For example: "I'm Tina Lionel, it's a pleasure to meet you."
nice to meet you. Thank you. ^^
