Busy, you take tons of calls.
Learned to improve my customer service and call handling technique to ensure metrics as call time and customer satisfaction.
Management is great, they are there to support you but not behind your neck.
Culture is the best I've ever seen, is the first thing you learn and keep it for good!
The stress, as you have to keep up the energy level through the day no matter what to show a positive attitude to the customers.
Internal events, feel like they care about you.
