Graduates should expect to work 12-hour days and 6 days a week to really master their jobs, says JPMorgan exec Summary List Placement Graduate wealth management analysts should expect to work 72 hour weeks and they''ll be better trained for it according to a senior JPMorgan executive. Mary Callahan Erdoes, the CEO of JP Morgan Chase''s Asset and Wealth Management division, was speaking during an episode of Bloomberg''s Wealth with David Rubenstein. Erdoes said that working longer hours will help graduate analysts learn their craft more quickly. Based on the idea that it takes roughly 10,000 hours to gain "base-level mastery" of something, it''s going to take around five years if someone works eight-hour days, five days a week, said Erdoes. "On Wall Street, it''s more like 12 hours a day, six days a week. That cuts you down to about two-and-a-half years before you become mastered in something." Once a graduate has that experience under their belt across different areas of the wealth management division they be sorted into a specialized team, based on what they''re best at, said Erdoes. The concept of the ''10,000hour rule'', which was made popular by the sociologist Malcolm Gladwell, is disputed by some.
