Pros
The only real pro is expanding your vocabulary. You learn corporate/legal jargon, so this is helpful if this is your first job in a professional setting. It is definitely a stepping stone, and should be used as one - work there for a year and get out.
Also, the attorneys and staff (within your general level of experience) are great - those are the people you really learn from. However, knowledge does not pay bills in an inflated market.
Cons
Departments are consistently mismanaged. After the probation period (or honeymoon phase), you are treated as a run-of-the-mill, replaceable employee. Once understanding the goals of supervisors, ensuring they look good on their reports, regardless of whether your assigned matters suffer, the work becomes incredibly hard to manage since your time to actually work competes with checking off tasks that don't apply to states outside of their expertise (Florida).
Additionally, promotions are purely title-based and a means of ensuring you stay. Those fictitious promotions are also not to be confused with a salary bump, unless you consider $1 equivelant to expectations of a senior in the field. Even without a change in title, you will often be asked to take on tasks that will likely (1) fall outside the scope of your duties, but be expected to be completed with no additional training, or (2) you will be asked to perform them often with no change in pay.
