I had a phone interview, then got called the day after for information to get flown in for an onsite interview. I had two panel (3-4 managers) interviews on site. One before lunch and another after lunch. HR recruiter checked me in and brought me to the interview room. After first interview I was taken to lunch at their cafeteria. After lunch I was brought back to the interview room for another round of interviews. The interviews were heavily technical base. The team was very accommodating and help with questions you get stuck on.
