Practise more than arithmetic
A correct calculation can still answer the wrong question. Setup, unit conversions and interpreting a result are useful skills to practise alongside arithmetic.
This short form samples those skills. It describes performance on these questions, not the underlying cause of a mistake or your likelihood of passing an interview.
What the diagnostic covers
Recognition & Setup
Seeing what needs to be calculated, and structuring the equation, before doing any arithmetic.
Units & Scale
Keeping thousands, millions, billions, currencies, time periods, and per-unit values straight through a calculation.
Multi-Step Reasoning
Holding a chain of calculations together without losing the intermediate values or the business objective.
Calculation Fluency
Executing arithmetic cleanly and quickly enough that it stops competing for your attention.
Percentages, Ratios & Rates
Moving fluently between growth rates, margins, shares, penetration, and conversion — including reversing them.
Exhibit Interpretation
Pulling the right figures out of a chart or table and turning them into a business insight rather than a description.
CaseSnack measures performance on its own quantitative tasks. It does not predict or guarantee interviews, offers, or firm outcomes.
