Company goes through Account Managers like bottomless breadsticks at Olive Garden. By the time I quit there were only like 10 people remaining from a hiring class of over 30. The job is intense and difficult. The product is unfathomably large, and all the training in the world wont help in making learning the product less stressful.
The biggest con in my view is that you will absolutely positively never get ahead of your workload. Maybe at first, but eventually its going to stack up. And from then on you are always going to be burried. Its just the nature of the beast. The ticketing system is constantly in gridlock and customers are very aware of this, and you'll be floating there surrounded by a growing number of problems with nothing you can do about them. Everyone, including managers is aware of this and they adjust their expectations somewhat accordingly but this is still a psychological nightmare. You will always have that nervous feeling in the bottom of your stomach like you're not doing enough. Your entire shift. Every day.
