The vice-president of engineering at Google, Ari Balogh, also weighed in on the latest furore with an internal memo criticising the manifesto.

"Despite speaking very authoritatively, the author does not appear to understand gender", he wrote. For instance, he suggests making software engineering more people oriented to attract more females by pairing people together to create a more people-oriented atmosphere, as opposed to forcing women/minorities into engineering studies and engineering roles. The government is asking the company to provide detailed employee data, which Google is fighting.
