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.

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!

Hi,

Why can't you make a table yourself? It's just 2 formulas in Excel. You are applying for a consulting role and should be able to do these basic things.
