First round consisted of a market sizing case and a normal business scenario case study. For market sizing case studies, the logic in how you approach your final answer is the most important part, and that you can clearly explain your thought process. The final round contained three interviews. One was a written case which was very time pressured. Try not to panic, regardless of what you get done, and try to think about how you would proceed with your analysis provided that you had more time. The second interview was a normal case study with some general fit questions and chit chat. The final interview was a partner interview which was based around a case study but very conversational and not as structured as usual. Try to always be structured and communicate ideas clearly, and try to enjoy the experience as much as possible!
