Intuit is extremely process oriented as a company, and so is there interviewing procedure. I was referred in by a former boss, but my candidacy filtered through 'standard channels' nonetheless (rigorous adherence to process).
I began with a phone interview with an HR manager at HQ who did a basic vetting (she was very friendy and unusually down-to-earth, without being unprofessional), and on the basis of that, was moved to local interviews with a series of people with whom the position would interact. This happened very quickly - perhaps within 10 days. I then went to their Calabasis division campus and had a combination of in-person and speaker-phone interviews with about 5 different people ranging from executive higher-ups who would rely on the output of this position, to direct potential co-workers, to higher up mangers from 'sister' divisions that this position would interact with. I was in the room from about 9 am until 2 pm, and they brought me a sandwich (they offered t bring whatever my choice was), at about 12:30.
It was a grueling day, but at the end I was left with the impression that this is a company that really does care about how people interact and that they will be happy at the company in addition to being a good fit. I have rarely seen such a process oriented company, and it's terminology and approach can sometimes be heavy and dense, but it was short of being oppressive. In fact, I really didn't mind it.
The interview process reminded me to some extent of my post-MBA consulting interviews in its intensity, but somehow it felt a little more human. I didn't get the job (which I was hesitant about given the potential hiring manager, who I later found out left the company shortly after I had interviewed), but I feel that if you're going to go corporate, you could do much worse than Intuit. They genuinely seem to care about what they're doing, and I think there would be much to learn there.
