Pros
The ability to do work on ones own pace at a home office and a superior level of independence offered to field engineers is very unique. The pay and benefits provided is decent, but not comparable for similar roles in other insurance companies. The training provided is superior and will be greatly beneficial to anyone who goes through it.
Cons
The expectations from a field engineer are different depending on the manager you were assigned when you were hired, luck of the draw essentially. There is sometimes a huge focus on menial semantics and a lot of hidden information, or information not readily available to the field engineer, that comes back a few months down the road to affect your report qualities. These are invariably CC'd via email to half the senior managers explaining your error.
