Initial phone call was from the recruiter, and then went onsite for a 1-1 interviews with 4-5 different people. Each took around 30 mins. The interview was very standard questions - covering each section of the past experience, the new role, what kind of skill set they are looking for. The cultures within the company. The organization structure etc. Each interviewer will give you 5 mins or so to ask them questions. After the initial interview, move to the second round interview. Basically the same format but with different people.
