What advice would you give your 15-year-old self?

I would try to formulate an answer which fits into a consulting narrative. Here it would be, for example, good to use the fact that MBB appreciate when a candidate has a very diverse professional experience.

So, the advice would be: try to work as many different summer jobs as possible. Work at a fast food joint, at a retail store, in a factory, in a car wash, in a pharmacy – those field experiences will stay with you for the rest of your life and will prove valuable once you move higher up the social ladder :)

Hope this helps!

Best,
Daniel

Hello!

On top of the insights already shared in the post, the "Integrated FIT guide for MBB" has been recently published in PrepLounge´s shop (https://www.preplounge.com/en/shop/tests-2/integrated-fit-guide-for-mbb-34), adressing topics precisely as your question.

It provides an end-to-end preparation for all three MBB interviews, tackling each firms particularities and combining key concepts review and a hands-on methodology. Following the book, the candidate will prepare his/her stories by practicing with over 50 real questions and leveraging special frameworks and worksheets that guide step-by-step, developed by the author and her experience as a Master in Management professor and coach. Finally, as further guidance, the guide encompasses over 20 examples from real candidates.

Furthermore, you can find 2 free cases in the PrepL case regarding FIT preparation:
