Avantages
Intuit is great place for work / life balance -- you really can have a full life outside work. My manager would check in periodically for the whole team to make sure that everyone's workload was manageable. Additionally, Intuit provides a standard full array of benefits, as one would expect from a software firm of this size. For technical folks, Intuit provides a dual-track career path -- one leads to management, and the other leads to software architect. While there obviously is some availability problems at the high end, it appears you can stay "geeky" and make it pretty far up the career ladder. Software engineers appear pretty well supported. Although as an intern, I was in a cube, all full time employees had their own offices, and good support facilities at the new San Diego campus. Oh, and the intern program is very good -- lots of events (internal and external) and decently interesting work.
Inconvénients
As with any large corporation, there is some amount of corporate/MBA-speak. Review forms sometimes teem with motivational topic headings and other ambiguous-but-hopeful metrics, that you are supposed to review your past performance and plan ahead with.
