Summary: You spend a third of your life at work, says Jeremy Callais. “You can teach someone how to do banking. We hire people who we want to spend a third of our lives with. We tend to think that the customers like to bank with those people too.” Callais talks about his bank’s approach to hiring, leadership development and succession planning — including his own progression through the ranks and the bank’s conscious recruitment of younger personnel, including a CFO and two board members in their 20s.
