Hello everyone! Realised that division seems to be the hardest to grasp among the +-x/, and most often than not divisions are required to convert fractions into percentages ie. 5 in 6 people converts to 83.3% ie. the end product can't be rounded to a whole. Is there anyone who can provide an extensive conversion table or the link to one which encapsulates such weird fraction-percentage conversions? Thanks!

Hey there,

I made the following quickly on Excel. However, I wouldn't advise you to try memorise the whole thing, as it's a) a lot to try remember and b) doesn't have that much value. Rather, memorise the first column of the table (i.e. 1/2, 1/3, 1/4, etc.), then if you have a different numerator, you can just multiply by that number.

Good luck!

Hello!

Precisely for the high amount of questions (1) asked by my coachees and students and (2) present in this Q&A, I created the “Economic and Financial concepts for MBB interviews”, recently published in PrepLounge’s shop (https://www.preplounge.com/en/shop/prep-guide/economic_and_financial_concepts_for_mbb_interviews).

After +5 years of candidate coaching and university teaching, and after having seen hundreds of cases, I realized that the economic-related knowledge needed to master case interviews is not much, and not complex. However, you need to know where to focus! Hence, I created the guide that I wish I could have had, summarizing the most important economic and financial concepts needed to solve consulting cases, combining key concepts theorical reviews and a hands-on methodology with examples and ad-hoc practice cases.

It focuses on 4 core topics, divided in chapters (each of them ranked in scale of importance, to help you maximize your time in short preparations):

·        Economic concepts: Profitability equation, Break even, Valuation methods (economic, market and asset), Payback period, NPV and IRR, + 3 practice cases to put it all together in a practical way.

·        Financial concepts: Balance sheet, Income statement/P&L and Performance ratios (based on sales and based on investment), +1 practice case

·        Market structure & pricing: Market types, Perfect competition markets (demand and supply), Willingness to pay, Pricing approaches, Market segmentation and Price elasticity of demand, +1 practice case

·        Marketing and Customer Acquisition: Sales funnel, Key marketing metrics (CAC and CLV) and Churn, +1 practice case

Feel free to PM me for disccount codes for the guide, and I hope it helps you rock your interviews!
