The interview process for the role consisted in 7 interviews: 2 preliminary , 4 with more structured Business Case and a final one with the country managing director Each interview lasts around one hour and it is divided into three parts: 1. Brief introduction of the interviewer and of the candidate (⁓10 min) 2. Business Case (⁓40 min) 3. Q&A (⁓ 10 min) My advice is to practice a lot before the interviews since most of the cases are taken from real projects and it is useful to have some basic structure in mind to try to address the problem at first. Of course do not try to solve the case mechanically: be creative and adapt all frameworks if you use them Be prepared to make quick mental math as most of the cases are heavy in numbers and don't be afraid of asking questions if something is not clear During the interviews i have experienced all types of Business Case (Profitability, Market Entry..), most of them had an initial part of market sizing embedded. There is no industry focus, it depends a lot on the interviewer so no need to have prior technical knowledge Good Luck!
