Interview had 4 rounds.
1. 30 mins HR Round
2. Interview with Regional Director/VP.
3. Interview with Senior Manager.
4. Case Interview.
Interview was pretty standard. If you are actually doing what they are seeking it is much easier. Very qualified people come to interview candidates, so don't approach it casually.
The HR are recruiting team is a thorough joy to work with. I had worked with a person whose initials were (DH). It was a pleasure working with him. He helped every step of the way and was available to talk before every round. From day one they ensured it was a good experience for candidate. Though I didn't get chosen, I have no hesitance in telling this was my best interview experience in my whole career.
