Overall 1 word: LONG.
The interview process was 7 hours with 10 people. First a meeting with HR, then the actual interviewers. They came in pairs and asked - in my opinion - excruciatingly basic questions.
Besides a couple technical questions from the first two people, I didn't get a single technical question over the course of 7 hours.
I was actually a bit disappointed as I had spent a whole week reviewing my experience and preparing for the interview.
