I worked with a recruiter as well as HR directly. First I took a personality quiz, then I had a phone interview about 3 weeks later and another 3 weeks later I had a 3.5 hour face to face interview. The interview was broken into 4 parts. I had 2 - 1 hour panel interviews, then I had a 45 min interview with a VP and finally the last 45 mins was with the director.
