Mayer revealed the inside story of her frame of mind when Yahoo gave her a call on came calling on June 18th.
"I'm doing a CEO search. It's a Fortune 500 company. It's in the consumer Internet space. It's in Silicon Valley - you wouldn't even have to move. It's the perfect job for you. The board is asking for you by name. Are you interested? It's Yahoo.
According to Mashable, Mayer wrote that she had gotten similar calls before, but was intrigued because she was a Yahoo fan.
But there one major problem. Mayer was 28 weeks pregnant and was looking forward to a "glorious six-month maternity leave" after 13 years at Google.
Despite the truncated maternity leave, Mayer reports that everything is working out fine.
"I've now been at Yahoo for eight months, and I'm having a ball - there are great people and terrific ideas. It's hard work, but I love to work hard. At the same time, starting a family with my husband has been all I hoped it would be and then some - joyful, intense, challenging," she wrote.
