Pros
As a Special Agent, you get to see the world. Your decision making skills and negotiation abilities will be tested and sharpened.
Cons
Special Agents are disposable. There are three phases to a career: Phase I - Investigations; Phase II - Protection; Phase III - Post detail. Phase II is the only phase that matters. Full time protection is the true mission of the Service. You will not be home. Your schedule will change daily. You will work day shift, midnight shift and afternoon shift, in the same week. Supervisors will tell you lies and mislead you on a regular basis, and if you question an obviously lie, retaliation will be swift. Once Phase II is complete, Special Agents are banished to a big city office like Miami, or the purgatory that is Washington Field Office. Phase III agents are disposable. This alone shows a true lack of character at US Secret Service headquarters.
