Brainstorming Questions

Great that you've already looked into what you should be focusing on. 

I wouldn't recommend a particular case book. Typically, the examples from most business school case books are not great.

You might find the following guide useful:

• • Expert Guide: Mastering Structuring & Brainstorming

You might also want to get expert support on how you are currently approaching brainstorming. That's likely to have the biggest impact.

Best,

To effectively brainstorm during a case, you need to ensure 3 things:

• Structure your ideas – Group your thoughts into 2–4 clear categories to stay organized
• Develop sub-ideas – Break each category into specific, actionable points to show depth
• Work under time pressure – Practice generating structured ideas quickly, prioritizing clarity and impact over quantity

This approach keeps your thinking organized, practical, and confident, even when the question comes unexpectedly. 

Many people make the mistake of not structuring responses to brainstorming/creative questions. It is also important to realise that even follow-up questions asking for more detail can be a test of your brainstorming skills.

Good luck for the interview! 

Hi,

Thanks for your question.

While I am not aware of any specific books, consider creating structures and buckets for brainstorming questions,. They are testing for your creativity and approach to solving any problem.

For the creativity piece, reading business articles to broaden your knowledge around different industries is a good practice. If you don't know anything about a specific topic, then try to look for analogs/proxies and using those to brainstorm.

All the best for your interview.

Good brainstorming prep material is genuinely hard to find. Here is what actually works:

• Take any business problem and give yourself 60 seconds to generate as many ideas as possible, then organize them into logical groups
• Do this daily with different topics. The topic does not matter. The habit of generating and organizing quickly does

What impresses interviewers is not the number of ideas but how cleanly you group them. Practice generating ideas in MECE buckets as you go, not just listing things randomly.
