Typically, math in case interviews is usually tested in the following ways: 1. Basic Arithmetic OperationsThe foundation of any mathematical task is basic arithmetic: addition, subtraction, multiplication, and division. Quick and error-free calculation, either mentally or on paper, is crucial.2. Percentages and FractionsPercentage calculations and working with fractions are often part of case interviews. You should be confident in calculating percentages and converting fractions to decimals and vice versa. This is especially relevant for tasks such as capacity change or profitability analysis.3. Estimation QuestionsEstimation questions test your sense of magnitude and your ability to quickly provide plausible numbers. Practice making rough estimates for various scenarios, such as the size of a market or the number of customers in a store.4.
