Having said that, the call centre industry has a high level of irate customers calling in usually. The primary reason a customer will call into a call centre is because they are unhappy or have concerns regarding a bill or service. This can result in very colorful language and people skills are not to be underestimated in this field.
If you are the type to lose your temper easily or to take strangers opinions to heart, this is not the field for you. If you're able to stick to company policy and focus on creative means to resolve a complaint in a fast manner, this can be a good job. Most of the tools you'll require are at your fingertips and it's mostly a matter of quickly identifying the customer's needs and how you can make them happy while staying within the company's guidelines. Most call centre's want each call to be resolved very quickly, so slow methodical practices are not going to serve you well in this field.
