Big Boss Interview is where the most high-profile chief executives and entrepreneurs come to give you their insights and experiences of running the world's biggest and well-known businesses. The series is presented by Sean Farrington, Felicity Hannah and Will Bain, who you'd normally hear presenting the business news on BBC Radio 4's Today programme as well as BBC 5live's Wake Up To Money. Each week they'll be finding out just what it takes to run a huge organisation and what the day to day challenges and opportunities are.
