It is best to wait until the employer wants to make you an offer before salary is ever discussed. The Day of the Interview Arrive 10-15 minutes early. Allow extra time if this is your first time visiting the employer site. Prior to the interview, obtain clear instructions about parking and interview location. Take notes when appropriate.
Meals are often part of a second interview.
Demonstrate good social etiquette and conversational skills during the meal. Remember the meal is part of the interview and you are being evaluated. Observe the work environment. Clarify the next step in the employer's decision making process. If you receive a verbal offer, ask for a written offer to be sent to you.
