Pros
I like the overtime. I really need it and it is there for me much of the time. Sometimes there are incentives to earn time off if you work overtime. Not having to spend money on gas is really nice. It has helped hone my communication-skills and work under pressure. Customer service isn't really that hard when you actually know the material. I can live on my wages as a single person in an apartment, and there are periodic raises, so that's nice. I haven't made any attempts to move up, but they haven't been hiring for management for my campaign yet. The managers listen to you, answer questions is as a timely manner as they can, and generally improve things that need to be improved, although a bit slowly. They are always bombarded with stuff and sometimes you have to remind/ask them twice, but as long as you really show you care you will earn favor with them. Being proactive in your learning, and creative with the tools you are given and seeing how far you can bend the rules for the customer with the manager's approval will show that you care, and earn you favor. With enough planning, you can travel to other states for stays and bring your equipment with you and do the job from there as long as you still work your shift. Sometimes the steps and procedures don't make ANY sense. but generally the management is very receptive to changing procedures that don't make any sense, or providing solutions for them in other creative ways.
Cons
There is a TON of stuff that you have to learn and you are always updating and refreshing your knowledge. This can be a real challenge. The official information-sources aren't updated as much as they should be and you have to be a sleuth sometimes to really dig and find information from a multitude of sources, ask a lot of questions and synthesize them into a comprehensible package for the person on the other end. I feel like there is a lot of wasted energy just finding the answer to a simple, albeit obscure question. There is a lot of red tape to execute some functions that shouldn't need it, but are abused by those who don't know what they are doing. They don't give much time off - I would rather start off with a certain amount of time off banked per quarter/year or something but I guess this is the trade off with the amount of overtime and the stability of the job. The technology can be slow, which can cut in to handle time.
