The onsite interview last 7-8 hours and consisted of a series of 1:1 interviews in the morning, followed by a lunch and tour, and then 2:1 interviews in the afternoon. Each interviewer asked 4-5 behavioral-type questions. The large number of behavioral questions for a technical position made for a very long day. After interviewing in Feb. and contacting them several times afterwards, I finally received an email four months later saying they had found someone else (although it turned out they decided not to hire anyone).
