Steve Ballmer, former Microsoft CEO, used a math game during job interviews at the company to evaluate candidates. The goal was to identify a characteristic he considered essential in a potential worker.
The game allowed Ballmer to see if candidates really knew how to make good decisions. This approach was used as part of Microsoft's selection process.
Ballmer, who led the company for several years, sought through this simple method to identify professionals capable of demonstrating logical reasoning and decision-making ability in concrete situations.
