McKinsey & Company uses a suite of gamified problem-solving assessments as part of its hiring process. These guides break down each game's objective, scoring rules, and the strategy that maximizes your score — written by consultants who've sat the assessments. Use them alongside our Ecosystem Solver, Sea Wolf Solver, Sea Wolf Simulation, and the BCG Quant Simulation.
