"Companies depend on sales consultants to establish trust between clients and companies through their marketing, interpersonal, and customer service skills. Expect to draw heavily on previous experience during an interview. Popular questions ask about situations in which you have changed a client's mind or demonstrated strong interpersonal skills during challenging times. You may also have to demonstrate your sales skills by pitching a product to the interviewer."

I always have a positive and inviting attitude and try to make the customers smile or laugh. I often had people call the manager just to tell them how nice the cashier (me) was to them.
