Happy new year to you too!
Process is similar among MBB, with sligh differences. However, the 4 types of questions FIT can have are found all across MBB -and other consulting companies-.
If you are looking for materials, 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)
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 3 free cases in the PrepL case regarding FIT preparation:
