have some experienced in one of the call centre of united states......This work sucks not only for international...but people from here also feel this job sucks....you will deal with different types of people continously in a day.........and not all people are same....some people are rude some are nice....if i remember the rude people i just hate it.....I didn't see non of those people who work in the customer service satisfied...some of the customer will yell ...its part of the job...those types of rude people are rude equally with all types of people....they dont' care and are not ready to listen......... Just my experience...
