For many candidates, the final stage is an assessment centre or onsite round, which may include multiple tasks: a group exercise (testing collaboration and communication), a short individual presentation (often 5 minutes, assessing your ability to distill complex insights for a non-technical audience), a case study interview, and one-on-one interviews with senior consultants or partners. Each component is designed to evaluate both your technical depth and your consulting potential, especially your presentation skills and ability to engage diverse stakeholders. Prepare by practicing clear, confident presentations and by reviewing frameworks for structuring data-driven recommendations.

2.6 Stage 6: Offer & Negotiation
