Case skills: articles and guides
Every consulting test and case interview leans on the same core skills: quick and accurate arithmetic, reading a chart correctly the first time, sizing a market from a few assumptions, and structuring a problem so that nothing important is missing. They are learnable, and they reward short daily practice more than long cramming sessions.
This hub collects our articles on those skills. For hands-on practice, the free case library has full cases with exhibits, and the drills cover math, charts and market sizing.
Which mistakes cost candidates the most?
Treating the online test as an afterthought, practicing without a timer, and neglecting the math. Our article on mistakes that end applications early goes through each one and what to do instead.
