Two companies, both (quasi) monopolies in their field.
Company A built its fortune by exploiting people.
Company B built its fortune by building (somewhat) decent products.
Company A developed a very advanced approach to hiring: specific questions to assess a candidate’s psychometric profile, screens to weed out bad choices, and a laser focus on the "top 0.1%".
Company B made it very public that hiring well is vital and encouraged every employee to think about it and participate. They even published an Employee Handbook years ago [0]
Today, many startups copy Company A’s playbook: crafting advanced questionnaires, trick questions, and trying to detect behavioural traits in their candidates.
No startup (that I know of [1]) has adopted Company B’s strategy.
Take your pick on who Company A is. Company B is Valve.
