I went through a phone interview and an on-site interview. The on-site interview took a whole day including two interview sessions and a presentation session. The interview mostly focused on personality and skills review.

Pretty standard for first round interview. Mostly interpersonal/social with some technical oriented questions. It seemed pretty fair for initial contact but may draw out into multiple rounds of interviews. The interviewer was personable and I didn't think they overstepped on reasonable questions about past work experience and how those experiences have been incorporated into guiding principles.
