In an interview to BBC Radio 4's Desert Island Discs, Sandberg confirmed that she experienced self-doubt while studying at Harvard, and realized that women underestimated their worth more than men.
"We need to start paying women well and we need the public policy and the corporate policy to get there", she told the BBC. 'Beyoncé's message that women can run the world is so important for little girls - and boys - to hear, ' said Ms Sandberg, 47, who has campaigned with the singer for gender equality. "Certainly, women applying for jobs at the same rate as men, women running for office at the same rate as men, that has got to be part of the answer", Sandberg, the author of the 2013 book Lean In said.
Her comments appeared to reflect Sir Philip Hampton, from GlaxoSmithKline (LON:GSK), who has been given the role to work to remove barriers preventing women from rising to senior business posts. He came under fire last week after he said he had "never, ever had a woman ask for a pay rise".
Ms Sandberg said: "What I really believe is that we start telling girls at very young ages not to lead, and we start telling little boys to lead, and that's a mistake". "I believe everyone has inside them the ability to lead, and we should let people choose that, not based on gender, but on who they are and who they want to be".
She also talked about her grief following the death in 2015 of her husband Dave Goldberg.
Speaking about a meeting with British interior minister Amber Rudd, she said the company and the British government were "very aligned in our goals".
