Pros
It's Government. Stable steady work year around. Opportunity to advance if you're willing to move or commute ridiculous distances, and you're good at test taking.
Cons
It's Government. Plan on having to accept a position where you can't afford to live, then promote closer and closer to your intended location. It's Government, so plan on taking tests to demonstrate your worthiness to advance. It's Government, it's nearly impossible to get fired for incompetence. Makes it a safe haven for culls. It's Government, so a lot of tasks you do makes no logical sense, but that's what some engineer in Sac said to do so you do it, i.e. cut all the willows out of a drainage ditch in the winter, then that summer plant willows in the ditch across the street and dump thousands of gallons of water on them every week because it's summer and the ditch is dry.
