You have to be extremely careful in hiring customer support people. The people whom you hire are going to represent your company and as far as the customer is concerned they are the company.

Think about the last time you walked into a car dealership or a cellphone company or any store and had a bad experience with one of the sales / support staff. Didn't your perception of the company / brand change immediately for the worse? Your Customer support people are the face of your company. So take care and hire the best!
