Lengthy but very thorough. The first stage of the interview was with the manager for an hour, discussing technical and behavioral questions. The second stage was about 3 hours. I presented for 45 mins, the rest was QnA. They then do a half hour session of work they do and you may ask questions.

Applied in February, but position closed due to internal problems. It reopened and then I received an email from the person who would be my supervisor to apply. I did, and then a phone interview was scheduled. During the phone interview, discuss some work ethics, the nature of the project, the goals of the project, my contribution in lab, salary range, etc. I wrote a quick email in thanks and waited two weeks. About one month later, I was scheduled to fly in for on-site interview. I gave a seminar and then met with 11 people that day from different departments.
