Pros
Free food. You are free to leave.
Cons
Be sure to research the founders, Michael Pousti and Brandie Williams-Smith. I wish I had. Be sure to research their past companies, SMS.ac and FanBox...they had many legal issues related to employee relations as well as fraud and other problems. You will be asked to work for little or no pay, so you can "change the world" which is really just an online MLM thing. Even if this is your first job and you're desperate, don't accept an offer. You will regret it. The founders have a very bad reputation among VC's and the general San Diego tech community. They have to hire very junior people, usually from somewhere else, because nobody who knows what they're doing will work for them. Pousti has no moral or ethical hangups about treating people poorly, using them up, and then tossing them aside like used tissues. He will promise that you will become a zillionaire, but just search through LinkedIn and contact any employee at the companies mentioned above and see how that turned out for them.
