Pros
If you're looking for a job that will constantly teach you, make you better, has great colleagues, and rewards you for performing at a high level, this is a great place to work. It's definitely fast paced but that's what makes it fun. Working here, you have the opportunity to work with high-level clients, be on the cutting edge of changing technologies, and be the best of the best in the political digital space. Plus, you get to wear whatever you want.
Cons
When it gets closer to Election Day, and depending on how high-level of a client you are dealing with, you'll be putting in more hours than normal. (If you expect otherwise, politics probably isn't for you.) But it is a great experience you will rarely get elsewhere and once it's over, you will have learned a whole lot, have experience under your belt, built connections (esp. on client strategy side), and will have time to enjoy the holidays that are right around the corner after Election Day (Thanksgiving, Christmas).
