Pros
Great work/life balance which is much better than almost all other software companies I have heard of. Many people here have families, and this is a big differentiator for Intuit to attract talent. Intuit is very well run, from a senior management perspective. Executives come from a wide range of industries, even outside of computer software. Not that many people are still around from the start-up days, so most are experienced managers and business people instead of just technologists who had a good idea but can't run a company. People tend to be very respectful and easy to work with at Intuit, and projects are generally not ego-driven. Intuit is, surprisingly, a good place to start your career. More junior employees are respected and even looked to as a source of new ideas. Intuit also has several rotational programs for new college hires, which helps when you don't absolutely know what you want to do, or don't have a lot of business experience.
Cons
Intuit is a more mature company, so you are unlikely to make a windfall from options. For people who may want to trade off their personal life and work harder for higher rewards, that won't always be possible at Intuit. Intuit is not currently considered one of the more innovative Silicon Valley companies, the three main product lines (QuickBooks, Quicken, TurboTax) have been around for a while. Efforts are under way to generate more R&D and new product ideas, but it still remains to be seen what will come of it. Consumers actually have to pay for Intuit products and services, and with the glut of new free, ad-supported competitors, Intuit is under some pressure.
