Bob Bechek, the worldwide managing director of Bain & Company, started his internship with Bain 30 years ago. Known for his modesty and self-deprecating wit, Bechek endured the same learning curve as any young consultant, particularly in recognizing just how much there is to master. Poets & Quants sat down with him to learn the lessons he gained as an MBA at Harvard Business School and the advice he would give today's students. "My advice is don't be afraid necessarily to stay in one place and build something significant," he said.
