Pros
I have worked for a number of carriers and can say this company is the first to do what they say and say what they mean. Sure, they make mistakes but it is there ability to recognize those errors and quickly change directions. This company is not for everyone. Working from home does not mean sitting around with your feet up. You work for a solid eight hours everyday. Some people love being at home and other need more interaction with others. They do review a ton of estimates. This is GREAT for the carriers. It is fine as an employee, as long as you can take constructive feedback. You are not going to "slip something by them." If you are not afraid of hard work, don't take feedback as a personal attack and like change, this is the place for you.
Cons
You need to understand yourself. If you need face to face interaction, this is not the place for you. You will speak to a lot of shops in a day as a negotiator. Some shops can be mean and you need to be able to handle that. Estimators have limited interactions with shops and customers. This can be nice or lonely.
