If I remember correctly, there was one or two phone call interview getting to know you and your background. Then superday with around 3 rounds of interviews. Everyone was very friendly.

Contacted by HR for a phone screen. After that, a 45 minute phone interview with a Director. Flew me out for a cocktail party and super day. Super day consisted of 4 interviews with senior management. Received an offer 2 days after the super day
