Pros
Given the extremely high workload you will learn how to effectively manage every second of your day. It is true that they promote those who work hard, but that comes at an expense (See cons).
Kontras
They use the "casual work environment" and "open office" to tout that everyone has a voice, but the reality is all the decisions are made at the top and everyone else is just a pawn to execute them. There is absolutely no pride in the products, it's amazing how this company has managed to take the fun out of beer. The workload is completely unrealistic but they keep trimming headcount - the culture dictates that you say "Yes" to everything, else consider your next promotion gone. Everyone is so stressed out that there is lots of fighting and tension between people who are supposed to be working together. If you have a life outside of work (Hobbies, Family, etc..) then you are seen as not "committed" to the business, be prepared to be on call 24/7/365. Being an American hampers your ability to move up, if you are not a Brazilian male who speaks Portuguese then your prospects are limited.
