In the United States, The Mackenzie Institute is a hugely successful management consulting and accounting firm. It typically hires people with academic degrees in economics or MBA from a prestigious university such as Harvard or Stanford. After reviewing resumes and GPAs, the company asks applicants how many tennis balls are produced in the United States each year. It usually hires people who guess the number of people playing tennis, the number of tennis courts, and so on. Such encounters and questions are typical of traditional businesses. I believe the best answer is to Google it! Accounting and analysis are relics of a bygone era. The era of diligence-averse venture capitalists has arrived.
