What are the McKinsey Solve Games?
The McKinsey Solve assessment is a suite of digital games developed by Imbellus, a cognitive assessment company acquired by McKinsey in 2021. It replaced the McKinsey Problem Solving Test (PST), a traditional written case-maths paper, as the firm's primary early-stage screening tool for new hires worldwide.
- Measures cognitive traits: systems thinking, critical reasoning, and decision-making under time pressure
- Candidates are assessed through immersive simulations, scored automatically with no interviewer subjectivity
- Used as McKinsey's primary early-stage candidate screening tool worldwide
What games are included in the McKinsey Solve Games?
The Solve assessment includes two games, each testing different cognitive skills under time pressure.
- Redrock Island: A 35-minute case study across four sequential phases. Candidates interpret data exhibits, perform calculations with a built-in calculator, and submit a structured written recommendation.
- The Sea Wolf: A 30-minute optimisation game across three ocean sites. Candidates select three microbes per site whose combined attribute averages and traits satisfy each site's specific constraints.
