Format
What the Boston Consulting Group assessment centre looks like
First Round — Case Interview
40-50 minutes1 interviewer (Manager/Principal)
Candidate-led case interview. You receive a business problem and work through analysis, data interpretation, and recommendation.
First Round — Experience Interview
30-40 minutes1 interviewer
Behavioural interview testing leadership, personal impact, or problem-solving. Similar to McKinsey's PEI format. Deep dive into one story for 15-20 minutes.
Final Round — Case Interview
40-50 minutes1 Partner
Harder case with more ambiguity. Partners probe your assumptions and test your ability to think under pressure with incomplete data.
Final Round — Experience Interview
30-40 minutes1 Partner
Deeper experience interview with more senior interviewers. Tests cultural fit, maturity, and self-awareness alongside leadership evidence.

Intellectual curiosity
BCG invests heavily in research (BCG Henderson Institute). Show interest in ideas beyond your degree.

Avoid
Common mistakes at Boston Consulting Group assessment centres
Jumping to conclusions in case interviews without laying out a structure first. Always pause, structure your thinking, then proceed.
Having only one anchor story. Different interviewers test different competencies — prepare at least 3 distinct examples.
Not asking clarifying questions at the start of a case. Good candidates confirm understanding before diving in.
Failing to synthesise at the end. Partners want a clear recommendation, not just analysis. State your answer, then support it.
Being thrown by unexpected case types. Practise market sizing, profitability, market entry, and M&A cases.
Treating the experience interview as less important than the case. It carries equal weight.
