What is the McKinsey Solve Game?
McKinsey Solve is a digital assessment used early in the recruiting process and replaced the McKinsey Problem Solving Test. The Solve Game is 85 minutes and includes 3 games: Redrock, Sea Wolf, and Sustainable Futures Lab.

Passed with a top score. The practice cases are the closest thing to the real test I've come across.
Did three sessions and felt ready. Nothing on the day surprised me.
Redrock Study was the one that clicked for me. By the second run-through I could feel my pattern recognition improving.
I was sceptical at first, but the simulation is genuinely close to the actual test format. The Redrock cases in particular were well-designed. Would recommend to anyone applying.
