Single in-person interview with potential future colleagues and directors which was around 6 people at the time. Single interview lasted approximately 1-2 hrs. Don't even remember if there was a phone interview at the time as I was contacted by a recruiter

Two round interview. The interview was tell me about yourself and why do you want to work there. Some technical questions. The interviews were held by the team members and they were very open to answer questions and they seemed busy.
