Hi, colleagues!
What do you think the most efficient way to prepare for brainstorming of ideas on different industries? I think I could make up the list of all industries, read McKinsey Quarterly on the trends of each industries, write them down and revise every day. Is it a good way to prepare for 'creativity' questions? For example, i failed the last case on banking I was not able to provide the interviewer with the exhaustive list of creative ideas on making credit cards successful since I am not quite familiar with the banking industry.
Thank you!
