Pros
StoryBox is incredibly well organized, tons of fun, with an exceptional "Get Stuff Done" attitude. Each day presents new challenges and obstacles that are collectively discussed as a team. Its an inclusive place to work, with a rare mix of work flow efficiency and openness to new ideas. If you're drawn to the idea of being on the ground floor with a hardworking team- StoryBox should be on your short list.
Cons
If you're looking to go through the motions and do the minimum, this probably isn't the place for you. If you're expecting a 6 week training program, also, probably not the place for you. On day one you'll be expected to contribute at a high level.
