Just like any other job interview, you must be prepared to provide whatever information is required of you. When it comes to beauty services, employers expect their staff to be friendly and polite. An upbeat personality attracts more customers, especially when you know that you have the necessary skills to give your clients what they expect. Employers will want to see if you are confident about yourself and what you can do. Be appropriately dressed and made up, and show self-assurance with your replies so that they see they are dealing with someone who knows what they are talking about.
