Engineering is a jeans and hoodie culture, and sales is more formal.

I have had a lot of setbacks that I have learned from.

From phones to cars to medicine, technology touches every part of our lives. If you can create technology, you can change the world.

We are a consumer company and our success is directly linked to our users trusting us. Therefore we have the same incentive as the user: they want to see relevant advertising so their experience of Google is positive and we want to deliver it.

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.

There are unlimited opportunities for display advertising. In fact, we're in the process of massive change in the display industry - how it's bought, how it's sold, and how it's targeted.

I love taking an idea... to a prototype and then to a product that millions of people use.
