Indra Nooyi sends e-mails all night.
"But," she says, "if I send an e-mail at 1.04am, I don’t expect an answer at 1.05am. I do expect one by 5!"
Kirsty Wark then asks her about working all night on a deal and being expected to work the following day.
Here, Nooyi is adamant.
"Once you make it to the C-suite, you have to recognise that flexibility and balance has all gone. Once you are there, there is no balance. A company can’t give you balances. It is a personal choice."
