Probably the best call center everThe good thingsFree cold/warm mineral water that you don't have to queue up to have. Free warm milo, coffee, chocolate, etc. They the nescafe maker that have a few options of drinks to choose from. Flexible time, great colleagues, bosses are amazing as they should be. Most fun and relax environment.
The challengesGetting to know the system and doing the troubleshoot if this is your first time, then this could be challenging! But it was my first time too and I had fun playing around with the systems! It may take more time to learn if you are not passionate with what you're doing. However in my case, it's pretty much easy as I really love my job and planning to build my career here.
