How Deloitte interviews Management Consultants

Deloitte, one of the Big Four, hires across audit, consulting, tax and advisory. Its modern process leans on online immersive assessments and a strengths-based final interview, designed to assess both capability and alignment with Deloitte's values and purpose.

For a Management Consultant specifically, Deloitte 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.
