There were two rounds of interviews. First round consisted of two case interviews, second round was one written case, and two 1:1 case interviews.
First round: My first case interview was with two interviewers - market sizing question. What's the size of the diaper market in Australia? I got bonus points for pointing out that diapers could be worn not only by babies, but also by the elderly. Some basic math to get to the final number. A few behavioural questions, but nothing that really stood out. Second interview was 1:1, some questions from my resume about why I chose my university and my extracurriculars. Case was about opening a B&B in rural France. Our client owns 1% of the investment. Expected revenue, expected occupancy, calculate ROI, as well as added benefits such as two free holidays a year. Numbers were quite straightforward, but remember to write everything down so you don't forget.
Second round: We were given a written case about an airline company making a decision about its flight routes. This was detailed in a stack of about 22 slides, and we were to answer a list of around 15 questions. Some heavy calculations, especially in the 45 minute timezone. Questions were mostly in order, and were quite doable given more time. It felt like a very intense exam. The written case interview with a manager started with some behavioural questions, then she went through the list of questions. I was pretty much giving a presentation, flipping through the slides and showing where I got the answer from. She questioned me about my final choice, and I had to justify it with all the numbers and strategic benefits I mentioned before.
The second case interview was with a partner, about health insurance. I think they were looking for ways to decrease costs: consolidating partner hospitals, engaging in promotional activities, encouraging better health (so fewer people will use the insurance), sponsoring healthy events/activities.
Final case interview with another partner was the most difficult. It revolved around those armoured trucks carrying cash. Who are their main customers? Why has revenue been falling? What can they do to increase them? There were tough numbers in this one, confusing percentages. Behavioural questions included what were the toughest decision you've made in a leadership role.
