Market sizing, profitability cases, candidate-led estimation, MBB interview prep.
MBB and tier-2 consulting interviews are case-driven. Standard formats include market sizing, profitability, market entry, and candidate-led cases. McKinsey leans interviewer-led with targeted probes; Bain and BCG more often run candidate-led where you drive structure. Behavioural and PEI rounds matter as much as the case, especially for senior hires.
Each interview here is a 20 to 30 minute live conversation modelled on real case patterns from 2024 to 2026. The interviewer probes for clean structure, quantified estimates with sanity checks, and explicit tradeoffs over hedged generalities. The scorecard separates structural reasoning from numerical accuracy so you know whether your gap is process or arithmetic.
