Pros
Most of the people who are account executive trainees are likable and easy to work with... you're all in the same boat and you support each other. You will probably make a lot of good friends. Also, you gain a lot of knowledge of the transportation industry through the initial training.
Cons
You are pretty much expected to fail. Even trainees that were used as examples of doing well in some of the training classes ended up getting fired in the long run. It doesn't always matter if you try really, really hard and make a lot of cold calls... sometimes the market just is bad, or you won't call the right people, and you will end up getting fired. But that's a sales job, I suppose.... but they really don't care if you succeed. No one gets too attached to each other. Just not a great environment to work in....
