Pros
You really do feel like you are making a difference at times. It looks awesome on a resume, and you have the opportunity to meet some great connections. Career opportunities aren't great at the Capitol, but you can move to other state agencies or become a lobbyist. Some departments offer telework days during the interim, and everyone works short hours during the interim.
Cons
Some departments (House Research for example) are absolutely fantastic with great leadership. Other departments have very poor leadership and communication, with inexperienced leaders who were just appointed by their buddies. If you end up in one of the later departments, you will feel like you aren't trusted or valued. It is extremely political (in not the right way) and cliquey. There is a lot of gossip and some are manipulative in tearing others down to build themselves up. Those that "play the game" are rewarded, while those that quietly do their job and stay out of drama become irrelevant and invisible. Innovation is also stifled, because of bureaucracy, distrust, and bosses who are scared you might show them up.
