It depends what kind of job you are after, the centres in the Birmingham and Dudley areas are more to do with the Customer services side of the business AFAIK.
If you are a good talker and like to sell or help people out then it could be the job for you. If you are on the phones you will use a headset.
Plus you get benefits of the type you would expect from a telecommunications company after 3 months.
Depending on the centre it will either be Virgin staffed or Agency staffed.
If they are advertising at present then give it a go, you have nothing to lose.
