Intuit was a great place to be a summer intern. The intern program is very well run, and interns are given actual projects to work on. We formed great relationships with other interns and members of the company. Everyone from new college hires to older employees to senior management were very involved in meeting with and getting to know the interns. There were many tech talks and other opportunities to learn more about the company and its direction. We got to meet the founder and CEO/CTO/etc. and had an opportunity to present directly to them at an "IdeaJam" (presenting unstructured time projects). Again, GREAT place to intern (and free corporate housing was nice!) I would recommend it to anyone.
Minpunten
Like any big company, there is a danger of stifling good ideas with office politics. There seems to be a genuine attempt to promote innovation and take risks with new ideas, though.
