Pros
I worked at Global Response for less than a year before I had to leave for personal reasons. I was in the call center department and compared to a retail job it is a lot better than that. It is very easy to obtain a job there. If you do not have a record and you have experience in customer service most likely you will be hired.
Cons
When I was there the turn out rate was high. That is why they are always hiring. If you do not make your talk time, holds and percentages there is a high chance they will let you go. In the call center departments you are answering calls from multiple companies. One call could be a person calling about cupcakes and another call is from a person needing to get their pool looked at. Its confusing because they want you to sound certain of yourself with the customer but if you can get any call from any business it is hard to become acquainted and familiar with the products that customers are calling about so you can give them correct information.
