How McKinsey & Company interviews Business Analysts
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 Business Analyst specifically, McKinsey & Company pairs its standard assessment with a technical bar focused on requirements elicitation, stakeholder management, process mapping. Business analyst interviews test whether you can bridge business and technical teams: understanding needs, mapping processes, defining requirements, and driving change. Strong candidates show structured thinking and concrete examples of delivering improvements.
