Avantages
Intuit is widely respected in Silicon Valley for being the first consumer software (Quicken) to break out. Founder Scott Cook shows up every day, still on site, imparting his vision to the employees. Intuit (through Cook) invented the customer-centric approach to software. That is still a very big part of the company culture. Experimentation, innovation, and design thinking are all championed here. Excellent pay and benefits (but note below what is the downside of that).
Inconvénients
Lack of diversity is a real hindrance to Intuit's 21st century growth. The execs are drawn primarily from Ivy League schools, + MBAs, with a finishing polish at a consulting co such as BCG, Bain, McKinsey. At the 5,000+ employee scale, politics are obviously going to be a crucial determinant. Because of executives' white-bread background, there's an additional weird veneer of niceness. Intuit's developers and managers all make bank. That's not so bad, right? The downside: People stay here forever, because they don't believe they could sustain their high salary on the open market.
