Met recruiter at a conference. About a month later I had a phone interview. 3 weeks later I was invited to the 2nd interview in Houston. I was in Houston for about 24 hours. The recruiters and interviewees had dinner the night before the interview. The interview lasted all morning and afternoon. We all gave a 5 minute presentation on our research and had 2 1-on-1 interviews. There were additional presentations about the company and a tour.
