How Boston Consulting Group interviews Management Consultants

BCG is one of the 'MBB' top-tier strategy consultancies. Its interviews assess problem-solving through cases and personal qualities through experience-based questions, with a digital screening step up front.

For a Management Consultant specifically, Boston Consulting Group pairs its standard assessment with a technical bar focused on case structuring (issue trees), quantitative analysis & mental maths, business judgement. Consulting interviews at firms like McKinsey, BCG, Bain and the Big Four test problem-solving under pressure. The case interview is the centrepiece — interviewers assess how you break a problem into a logical structure (often using issue trees), handle quantitative analysis, and synthesise a clear recommendation. The fit interview probes leadership and personal impact stories.
