Warren Buffett was rejected by Harvard Business School

American business magnate Warren Buffett, who is world's third richest person, was rejected by the Harvard Business School in 1950. "I spent 10 minutes with the Harvard alumnus who was doing the interview, and he assessed my capabilities and turned me down," Buffett recalled. Notably, the famed investor, having a net worth of over $66 billion, turned 86 on Tuesday.
