Tell me about a time when you made sure a customer was pleased with your service.
When working with a client or customer, always remember to put their needs first. Whatever requirements they have you must deliver.
Example- One of my customers wanted a table designed in a specific way with a particular kind of wood. I listened to all their requirements of him and adhered to them while doing construction. Keeping him up-to-date every day to know that we both are on the same page. After a few days, they delivered that table that met their criteria and we got many more orders.
