Avantages
I really like the people at Intuit. On the whole, they're very bright and focused on doing a good job for customers. The culture is supportive and management treats people with respect. I also like the work-life balance at Intuit. People tend to work from ~8:30 to 5:30 and most jobs don't involve much travel. It's also nice to work for a company with millions of customers. When I tell someone where I work they generally have used one of our products and have good things to say about it. It's definitely worth checking out Intuit as a place to work.
Inconvénients
One of the biggest challenges Intuit faces is moving from a boxed software company into selling services on the web. Management understands this and has set a clear vision but the company is likely to face a lot of bumps as it transitions. Intuit has a fairly slow moving culture where you have to create a lot of powerpoint decks and convince a lot of managers before you can do anything very dramatic. They also tend to be slow to promote people which can be frustrating. On the financial side, the stock has been struggling for a long time which seems to indicate that the market is skeptical of its ability to grow.
