Pros
I really enjoyed working here b/c I came from over the top, nose-to-the-grindstone chaos of my previous agency. Cake instilled in me the method to work 'smart'. That certainly met some cutting of corners and a bit of devious agency agenda setting. If you enjoy the pace of real time social media mixed with PR-driven promotions, then this is your place. But, be sure to know they will ask that you do more than you've been asked and help with a lot of event and content production, new business development, rubbing elbows with extremely difficult "partners" and (on the side of the spectrum) great clients. They do an excellent job of connecting you with their other offices around the world, too.
Cons
Not great pay in relation to the amount of work you'll put in. But, that's par for the course in PR/Marketing agency world. I worked there at a time when the office space was not ideal. I've seen the new office and it looks a bit better and more "formal" which you may read as stodgy, but I liked it. Leadership can be a bit tricky for people without thick skin.
