As a consultant in the customer service arena, you will be considered to be an expert on customer experience and customer satisfaction to the clients that you work with. While this question is certainly open ended, your interviewer is looking to hear that you have passion and belief in your answer because there is indeed no right or wrong answer to this question. Be sure to prepare for your interview ahead of time and be able to speak openly and passionately about what you believe is the most important factor for a satisfied customer.
"As I've worked in customer service my entire career in retail sales and in dining, I truly believe that the best customer experience is provided by happy and engaged employees. If employees are satisfied with their work and believe in the product that they are selling, they are able to speak to customers intelligently and wisely about the product and they do it with a big smile on their face. This factor is what helps keep customers coming back time and time again."
"I'm a firm believer that a positive customer experience, no matter the business or industry, comes from the basic human need of trust. Any customer of any business is inherently putting their trust in the company, the product and the associate that they are working with that the will receive a quality product and quality service. In projecting this out to those that provide customer service, there are many factors to building trust with customers. Being knowledgeable, being friendly and considering the needs of the customer are of utmost importance to gain trust. These factors are just the tip of the iceberg when it comes to building that trust."
