Pros
Corporate goals are in line with the company culture. People are honest, caring, driven, and have class. Everyone really cares about the customer experience - from leaders to new college-grads. You're also encouraged to be yourself, let your flag fly high - diversity (in all aspects), equity, and inclusion are taken seriously here. Internal mobility is also widely accepted and encouraged. Hiring manager think to look internally to fill roles, before looking externally. A focus on your personal health above work is prevalent - and expected. Taking time off to recharge or taking mental health days is also encouraged. You have an opportunity to work with a lot of big brand name products: TurboTax, QuickBooks, Mint, Credit Karma… and the people all have the same vibe!
Cons
It's a big company, so there are some of the typical big company issues. Some teams have micro-cultures that aren't always awesome, but you might be able to move out to a different team. Bureaucracy and socializing your work can sap you if you don't conserve your energy. Speed as a culture is constantly being broadcast, though, this can lead to teams doing duplicative work, since the company is big.
