The process is extremely demanding, not in terms of difficulty but in terms of time. They require in office presence even if the interviews are remote. These office visits can be lengthy (3h+). The interviews themselves consist of situational questions and working in case studies with the people you would be working with, you are not told anything regarding the exercises before but you can expect something related to the role. I had to chase HR to get an update which considering the time and effort spent is ridiculous.
