Pros
Not a single thing other than the guiding principles that no one really follows.
Cons
This is just another company created by Mark and Ethan, and with them came a few people from their old shop. Maybe they know, maybe they don't, but there is a grouping of those people and unless you fall into the crew, good luck. Getting a yearly review is a joke, and promotions are only to the favorites. Managers want things done their way, and regardless if you provide evidence of otherwise, you will not enjoy the environment. Don't be fooled of them saying they have done it before they will do it again. Most of those senior positions never had to deal with such a large business before and it shows. Waisting more time fixing issues that did not need to occur and wasted money where it matters the most.
