Quick Comparison Table: Big 4 vs MBB at a Glance

Prestige and Brand Perception: The direct answer

MBB wins on prestige. It is the strongest brand for strategy and leadership potential on a CV. Recruiters read it as evidence of structured thinking and executive presence.

Big 4 is highly respected, not identical. It signals trust to deliver complex programs in regulated environments, but it does not carry the same pure strategy halo.

Why candidates end up at Big 4 instead of MBB: two main reasons. First, the MBB interview bar is steep. Second, some candidates deliberately choose Big 4 to gain delivery depth, a specific city, or a particular practice. The brand gap still exists, and acknowledging it helps candidates plan their next step. See firm guides: McKinsey careers, BCG careers, Bain careers.
