The memo had a section dedicated to changing Google to make it more welcoming to women. It mentioned "pair programming" as one female-friendly culture change.
"We can make software engineering more people-oriented with pair programming
and more collaboration. Unfortunately, there may be limits to how
people-oriented certain roles at Google can be and we shouldn't deceive
ourselves or students into thinking otherwise (some of our programs to get
female students into coding might be doing this)."
