I never worked as call center customer service before. But my first job was IT support for a Telco. The call center of coz need 24/7 shift rotation. You will continuously answer call non stop. The team leads will monitor how long you go ular, toilet break, smoke break and stuffs . Basically you are glued to your chair and the headphone all the time. Expect to always kena marah from customer or people that are hard to deal with. Training will be provided. However I believe your job is contract basis right ??? You will lose out a lot of benefit.

There is 1 collection department also. That one I remember no need work shift. But keep asking people. " Encik bila mau bayar ? , Pakai credit card ke cash? "
