Pinky, are you asking if you MUST have 2yr customer service??? If you have been working for 2yrs or more then likely you have it... even if you were working as receptionist or serving sandwiches in a shop, it's all customer service. If you let me know exactly what it is you were asking I might be able to help you some more. Don't worry too much, I have 10yr customer service and STILL can't get an invite with EY...! Perhaps such a thing as TOO MUCH experience...
