My most radical shift was leaving Intel and joining Google, a small startup at the time, even though I was pregnant.

Even though it was a start-up with fewer than 20 people, and I was pregnant with my first child, the best decision I've ever made was to join Google in 1999. Worst decision? Deciding to get a puppy and a bunny right when the baby came.

I am responsible for creating and overseeing the future products that make up Google Advertising.

Let's face it: Engineering companies in general have more men than women. Google has tried really hard to recruit women. On the other hand, we have a standard. Google tries to recruit the best engineers.

Though we do need more women to graduate with technical degrees, I always like to remind women that you don't need to have science or technology degrees to build a career in tech.

First there's my role just as an executive being responsible for advertising, regardless of gender. I think that's a position that I take seriously. That's the first role. But I think for my role as a woman at Google, you try to set a good example and be a role model for the other women in the organization.
