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.
