BCG is reported to use BCG Online Case (the Casey chatbot) for numerical screening.
BCG's first screen is its own chatbot-led online case rather than a publisher test: Casey walks you through a business case and asks quantitative and qualitative questions, finishing with a short video answer. The quantitative questions are case-style arithmetic — sizing, percentages, share and growth from exhibits — under one overall clock.
Nobody can honestly clone BCG’s own assessment — be wary of anyone claiming to. What transfers is the core it measures: fast, accurate data interpretation under time pressure. Diagnose your gaps, train them, then prove it in a timed mock.
Employers change assessment providers, sometimes mid-cycle and by region. This page reflects publicly reported candidate experiences as of June 2026. Before practising, check the link in your invitation — it names the platform.

Yes — BCG Online Case (the Casey chatbot) includes genuinely numerical work: reading data exhibits, percentages, ratios and quick case arithmetic. The wrapper is bespoke, but the numeracy underneath is standard and trainable.
Train fast, accurate data interpretation under time pressure — that's the transferable core. The bespoke interface is learnable from the employer's own practice material; the numeracy is what needs real training.
