Many candidates struggle with the BCG case online because of common mistakes that can be avoided with the right preparation.

One major mistake is failing to structure responses properly—answers should be logical and well-organized. Time mismanagement is another common pitfall, with candidates either rushing or overthinking responses. Ignoring key business concepts can hurt performance, as the test evaluates business judgment. Additionally, neglecting to prepare for the final video pitch can weaken your overall impression. Avoid these mistakes by practicing structured problem-solving and timed case simulations.
