I'm in the middle of doing case interviews for a couple of firms, and I have now done about 15 case interviews. I now have some final rounds coming up, and while I've found that I've been very strong in market sizing/estimation questions, number/graph based cases and some of the more 'complex cases' - I've been struggling with some of the more 'simple' cases, many of which involve increasing revenue or some other quantity, and are to a certain extent open ended.
These are some questions I felt I didn't answer very well:
After talking about how I used to play competitive soccer in my college days I was asked: "How would you increase the number of spectators to your club soccer matches at your homeground?" after a discussion this was followed by: "It seems like soccer isn't that popular in your country.. How would you go about increasing the popularity of soccer in your country and doubling the number of people involved in the sport?
"How could XX airlines double their revenue from inflight food and beverages?"
"How would you reduce car accidents in your home town by 30%"
"How would you double the revenues from bananas at a certain grocery store?"
Also the latest question I was asked, maybe not so 'simple'
"You are an automobile manufacturer and you want to move into the luxury sector. Do you build your own brand or buy an existing one?"
Anyway I think the problem is that coming from an engineering background I have strong analytical skills, but struggle with structuring more open-ended or qualitative cases.
If anyone can provide some quick example solutions (even just the framework or the structure for the approach) to the above questions, it would be greatly appreciated, as I haven't really been able to get feedback on my performances.
Thanks a bunch in advance!
