The story in 5 parts

A closer look

Levy explains how Google's hiring process was built to find raw intelligence, with tough interviews and committees.

He shows how Gmail started as a side project and launched with far more storage than rivals.

The China chapter covers Google's struggle with censorship, ending with its decision to move search out of mainland China.

Levy also covers how Google used data to make product choices, testing small design changes with real users and keeping what worked. He describes engineers testing dozens of shades of blue for links. The book uses these stories to show a company that trusted numbers, sometimes to the frustration of designers who wanted more room for taste.
