The interview process was divided into 2 sections. The behavioral and the case study interviews, with each 30 minutes. The behavioral interview was the standard interview about "tell me about yourself" or "tell me a time when.." and there were about 3-4 questions. The case study one is one that most people find it challenging. You would get both qualitative and quantitative questions. The case for me was qualitative, quantitative and then qualitative again. I would say that the quantitative one was challenging, with real-life data. However, as long as you keep actively mentioning the thought process, actively listening and showing enthusiasm, that is what the interviewer is looking for.
