"Working in catering requires professionalism and excellent customer service. During an interview, expect to be asked about your flexibility, passion for the culinary arts, and skills that you can contribute to the company and client's experience. To ace your interview, come with an optimistic attitude to show that you can provide a positive service for events that you would be working."
What would you do if a client was upset with you on the phone?
Let the client talk, when there's a pause, tell them "I understand how you feel." That I would take responsibility and tell them I will do everything in my power to make this right by them and see to it that it never happens again.
