I have worked for 6 months as a CRO in HGS.It was very funny and tensionful work I experienced that time and as I continuously getting calls for 8 hours in a day from airtel customers, some are interact with a good language and some are very horrible.I learnt how to handle differant customers with our intelligence.
This is the best job for freshers and a good remuneration we get and finally CRO is the agent who directly connected with the customer who should have good communication and intelligence as well as patience.
