How McKinsey & Company interviews Management Consultants

McKinsey is one of the 'MBB' top-tier strategy consultancies. Its rigorous process assesses both problem-solving (through cases and the Solve game) and personal qualities (through the PEI), looking for future leaders who can structure ambiguity and influence clients.

For a Management Consultant specifically, McKinsey & Company 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.
