Pros
You will be working with some very smart and hard working people. There is a lot of ethnic diversity. Snacks, office bar, and office dogs. Free lunch, if you're ok with it not being super healthy. You can say you work at one of LA's hottest startups.
Cons
Lots of distractions in an open work environment, 3+ office dogs at any given time so definitely not a place for people with allergies or germaphobes. Management is temperamental and micro-managing. Be prepared for a lot of "negging" during interview and 1:1s such as, "you have the skills but maybe you need to prove your personality/passion" "you still have a long ways to go" etc., and be prepared to take a salary on the lower side of the spectrum. The team is very young, a lot of the more experienced people have left. Smart people have to shoulder extra work. Everyone else coasts by on pure enthusiasm and good attitudes. There is limited budget/resources. Expect to take extra time cobbling and hacking your way through projects.
