Pros
From my experience, Intuit really lives its values. Great drive throughout the company to innovate and move quickly, making it a fun and energizing place to work. I work remotely, and Intuit is very supportive of that for many positions. (About 10% of Intuit employees are remote.) There are many offerings and opportunities for personal and career development. It's easy to reach across business units to engage with people. Great annual and quarterly meetings where lots of information is passed down to all employees.
Cons
(This is't really a "con," but something to be aware of.) Intuit wants to keep growing and focus on profitable aspects of its business (this is a good thing.) They try to acquire a few companies each year, and the process of bringing Intuit's corporate culture to those acquisitions isn't always smooth or successful. Intuit will suddenly sell parts of the business that didn't work out (for one reason or another) or that aren't fully in line with where Intuit wants to go. For example, they bought Homestead in 2007 and then sold that business in 2012. These are generally good business decisions, but if you're part of that piece of the business, you could suddenly find yourself working for some other company besides Intuit. My advice is to keep your eyes and ears open about where the company is focused (it's not hard to tell) and seek out roles in those areas. After an acquisition was merged with my business unit, my role changed and I was under-utilized for a while. I had to seek out a new position because the old one wasn't challenging anymore, even though my title remained the same.
