I applied through a recruiter. I interviewed at Convergys in Apr 2013
Interview
Do not tell truth about the process. They will hire you saying customer service but once you complete the training, then you will see that it is hardcore sale process without any incentive. If you were supposed to get incentive, they will zero out by telling you minor issue which does not even matter.
Interview questions [1]
Question 1
Easy to be hired and all leave after a month looking at situation and the management
